Since applying Feb 2013 Sharepoint 2010 CUs - Critical event log entries for Blob cache and missing images

Question
-
Hi,
Since applying the February 2013 SharePoint 2010 updates, we are getting lots of entries in our event logs along the following:
Content Management Publishing Cache 5538 Critical An error occurred in the blob cache. The exception message was 'The system cannot find the file specified. (Exception from HRESULT: 0x80070002)’
In pretty much all of these cases the image/ file in question that is reported in the ULS logs as missing is not actually in the collaboration site, master page / html etc so the fix needs to go back to the site owner to make the correction to avoid the 404 (if they make it!). This has only started happening, I believe since feb 2013 sp2010 cumulative updates updates
I didn’t see this mentioned as a change / in the Fix list of the February updates. i.e. it flags up a critical error in our event logs. So with a lot of sites and a lot of missing images your event log can quickly fill up.
Obviously you can suppress them in the monitoring -> web content management ->publishing cache = none & none which is not ideal.
So my question is... are others seeing this and was a change made by Microsoft to flag a 404 missing image / file up a critical error in event log when blob cache is enabled?
If i log this with MS they will just say, you need to fix it up the missing files in the site but would be nice to know this had changed prior! I also deleted and recreated the blob cache and this made no diffference
thanks

The event log 'error' is benien. You can simply ignore it.
The error appears to have originated in the Feb 2013 CU, is present in the Apr 2013 CU, and yes, MS13-035 also introduced the change to the BlobCache.
If you're looking for a resolution to the Event Log errors, opening a PSS case would be the way to go, otherwise just ignore them.

Have you tried flushing the BlobCache?

Hi @all,
i´ve got the same error. Any ideas. Flushing the cache doesn´t help...

I´ve mentioned that in IIS the ASP.net authentification has been deactivated. After setting all active again in my sc´s and reconfigure portalsuperuseraccount/portalsuperreaderaccount the error doesn´t show up again!

Same issue here; also appears to be since the SharePoint 2010 Feb 2013 CU was applied:
An error occured in the blob cache. The exception message was 'The system cannot find the file specified. (Exception from HRESULT: 0x80070002)'.
Wednesday, May 1, 2013 9:42 PM -
Are you only seeing this with unpublished/unapproved content, or published/approved content as well? I could only replicate it, in the Apr 2013 CU, with unpublished/unapproved content. Any time I published/approved content, the file would be created in the blob cache.

After tracing a little deeper in my farm (using the correlation IDs), it appears the files that are erroring out for me are actually missing. As one example, we have a file that is referenced in a SharePoint branding farm solution, but the file is not actually in the folder where it needs to be. I just hadn't noticed the blob cache error until today while troubleshooting other log errors. I can't tell how far back in time the blob cache error entries go because my available usage data only goes back 2 weeks. So it looks like I can't provide any additional info on this topic.

I am seeing this exact behavior in my environment. Is there a fix yet? Or does the April CU fix this issue?
Thanks.

OK-so how do we bring this to the attention of those who can fix it? :)
Is it reasonable to believe that in the next CU this may be addressed?

You would open a PSS case.
However, I'm questioning the criticality of this error. When I did my testing, it only occurred on items that were unpublished/not approved. Anything that was published/approved did not experience this behavior.

I would argue that the severity is relative to the environment. How can I open a PSS case?
Thanks,
Jesse A. Brandenburg
Tuesday, May 21, 2013 3:35 PM -
Yes, but is that for unpublished/unapproved content, or published/approved content? Just because there is an event log error does not mean it is severe, just annoying :-)
You can start the PSS case here:
http://support.microsoft.com/get-support/more/
If you don't have a Premier contract, they run about $250 I believe. If it is a bug, you can ask for a decrement on the case to be refunded.

The way I looked at it was taking a single page with a single image. The image was unapproved/unpublished. When viewing the page, I saw the BlobCache error. After publishing/approving, I did not see the error (and also saw the the image present in the BlobCache folder).

We currently do not use the publishing/approval functionality. The content that exists is all published as a major version and approval is not required in any area that content is stored.
I am getting thousands of error messages.

Noticed that one reason for this is that page refers to /favicon.ico which is missing, and causing BlobCache to log error. Why is it logging to Application log for a missing file, is probably the actual question here - ULS log would be correct place for these kinds of errors.
Friday, May 24, 2013 12:58 PM -
It also logs to the ULS log: http://sharepoint.nauplius.net/2013/04/april-2013-cumulative-update-and-ms13-035-blobcache-errors/

There doesn't seem to be any, it does appear to just be annoying. Once an item is published and approved, the item is created in the BlobCache (assuming BlobCache is enabled) and the error no longer appears for that item.

Thank you, but as I stated earlier, all of the content in my farm is approved and published. The content that appears to be causing errors is .css files and .js files. I found this in the ULS logs under the 'Name' field. It specifies the full URL of what it is trying to request at the time of the error.
It does appear to be tied to a 3rd party (Bamboo Solutions). I will check with them to see if they have any documented incidents.
Thanks,
Jesse A. Brandenburg
Friday, May 24, 2013 2:31 PM -
It is not a 3rd party issue. Microsoft significantly changed the code in this area which appears to be causing the problem.
Do you have BlobCache enabled on the problem Web Application?

The only reason I say it could be a 3rd party issue is because the errors are all tied to resources provided by Bamboo. There is not one error I have found thus far that points to any other file.
Yes, BlobCaching is enabled.

Understood :)
You should have a line in the ULS that says:
Unable to cache value for URL /PUBLISHINGIMAGES/DIRECTX_PUMPKIN.JPG, error was System.ArgumentException: Item does not exist.
Does that point to an item that does exist in the BlobCache, or one that is missing?

I looked through the ULS for 'Unable to cache' and found several instances where it said a URL- actually for the Bamboo World Clock web part (free). and it points to a 'SpecialAffects.js'. It says 'File Not Found'. There are no .js files in the Blobcache.
I could not find anything when I searched for 'PUBLISHINGIMAGES' or 'Item does not exist'.
Is that helpful?
Thank you,

Friday, May 24, 2013 2:51 PM -
The URL won't be exactly the same. I wonder if that webpart somehow specifically excludes blobcaching, or if you have removed js as a filetype from the blobcache configuration in the Web Apps web.config.

That is a good thought. I verified in my web.config that |js|css| are included in the BlobCache inclusions. I found that there is an entry for <WebPartCache Storage="CacheObject" /> (I haven't changed anything related to that). I will check with Bamboo to see if they have any known conflicts with that webpart.

We have the same problem - thousands of the following errors in ULS:
Unable to cache URL /FAVICON.ICO. File was not found
The file is in place ..\14\TEMPLATE\IMAGES where it is expected to be.
Since it is in 14 hive it cannot be published or approved.Could anybody tell why this file is causing this (very annoying) error.
Monday, May 27, 2013 8:13 AM -
You're getting the error due to the file not being present in the BlobCache location.

Ok, but what is the reason that it's not getting into it?
We get this error only since this weekends maintenance window when some Microsoft security patches have been installed including MS13-035 (KB2810059). Before this we did not have problems with this particular file.Do you have any ideas how to get it into the cache again?
Thanks

I recently experienced this issue.
Had multiple entries in the event logs and also noticed the issue in ULS log (along with reference to not being able to cache /favicon.ico).
I updated the BlobCache location in the web.config to a new, clean folder. The cache started rebuilding and I haven't seen the error again. This also solved an issue where Display Templates were caching old versions and not updating to newer versions we were using.

Hi Brad,
The December CU 2013 seems to fix this issue, as described in the KB article of the coreserver component: .
For SharePoint Server you need to install the DEC Cumulative Update (which contains the coreserver component) from http://support.microsoft.com/default.aspx?scid=kb;EN-US;2849971
!!Note: Please test this in a test environment first, before deploying it into production.
Hope this helps.
Cheers,

Hi Jesse,
I realize this is a stale post but I did not see that you replied back after checking "with Bamboo to see if they have any known conflicts with that webpart.", from Friday, May 24th, 2013 post. I'm seeing the same blobcache issue for the "World Clock and Weather Web part" in SharePoint 2013 (Aug 2013 CU). No other image, file type, etc causes this issue and I see no resolution other that to try installing Dec 2013 CU for SP2013.
Thanks,
JeffThursday, February 13, 2014 5:29 PM -
Hi Jeff -
I am not sure what the issue is - they did not provide any solution. I am still having the issue and I am on the December 2013 CU.

I'm facing the same error on our SharePoint 2013 farm. We are on Aug 2013 CU and if the Dec CU (which is supposed to be the latest) doesn't solve it then what else could be done.
Some users started getting the message "Server is busy now try again later" with a corelation id. I looked up ULS with that corelation id and found these two errors in addition to hundreds of "Micro Trace Tags (none)" and "forced due to logging gap":
"GetFileFromUrl: FileNotFoundException when attempting get file Url /favicon.ico The system cannot find the file specified. (Exception from HRESULT: 0x80070002)"
"Error in blob cache. System.IO.FileNotFoundException: The system cannot find the file specified. (Exception from HRESULT: 0x80070002)"
"Unable to cache URL /FAVICON.ICO. File was not found"
Looks like this is a bug and MS hasn't fixed it in Dec CU..

Has this issue been resolved by any new patches that you know of? Constantly getting favicon error, removed ico from web config which has decreased errors alot but still getting random blob jpg/js errors about missing files that are indeed not in directories.....
thanks n advance

Just wanted to report that the Blob cache errors that I was seeing for the Bamboo World Clock and Weather Web part have disappeared after installing the SharePoint Server 2013 Service Pack 1 update. To clarify, this is for my SharePoint 2013 farm. It has been ten days now since installing the update and no new Blob cache errors. As a part of the SP1 update, Bamboo suggested that I follow the instructions on this page _http://store.bamboosolutions.com/kb/article.aspx?id=12772 because my Central Admin web app is on a different server than the WFEs. The suggestion was a result of some separate, Bambo specific XML errors I experienced when attempting the SP1 update in a second (test) SP2013 farm. Bottom line is, I don't know if the SP1 update or the Bamboo instructions fixed the Blob cache errors for me.
