Thursday, November 26, 2009 3:57 AMOn each restart of an Exchange 2010 server running on Windows Server 2008R2, Event 12025 and 14 instances of Event 12027 recur. This also happens when the MSExchangeTransport service is started. Each instance of Event 12027 references a different category of performance counter.Event 12025 text: Transport service is disconnecting performance counters with process lifetime from their old process.Event 12027 text: Transport service did not disconnect performance counters with process lifetime in category: <category name> from their old process since the file mapping for the performance counter was not found.How to eliminate these events?

I get the same thing on our hub servers, but haven't looked why or cleaning them up. They don't *seem* to be harmful, but I have nothing really backing that up 100%.

Thursday, November 26, 2009 3:22 PMThanks, Brian.I saw these events on an earlier installation of Exchange 2010 RTM, and thought I had something configured incorrectly. Now, having seen them again on another of my own installations and having read your post, I think they commonly occur.
Friday, November 27, 2009 9:02 AM+1 on this issue.
I've built about 4 Exchange 2010 RTM Servers now and they all have the same issue.
Thursday, December 10, 2009 9:51 AMJust installed Exchange 2010 RTM Update RollUp 1 and this error is still here.
Thursday, December 10, 2009 5:40 PMSame here: 1 instance of 12025 and 14 instances of 12027 every time the MSExchangeTransport service starts; Update Rollup 1 did not fix this (if in fact this is a bug).
Thursday, January 14, 2010 1:28 PMYes, I can also acknowledge that the problem seems to be occur on every Exchange 2010 installation on Windows Server 2008 R2. Any comments from MS?
Thursday, February 18, 2010 8:41 AMHi everyone,
I had got same errrrrrrrrrrrrrror on our HUB&CAS Exchange,I didn't find solution for this..
Wednesday, March 17, 2010 9:52 AM[bump]
Any developments on this issue?
Safe to ignore?

Count me as another one with the exact same symptoms. It's annoying to see these warnings every time, but my Exchange Server is functioning fine. It's encouraging to see that this "problem" is fairly common, but I would like it if M$ would fix it.
Tuesday, March 30, 2010 1:31 AM+1 on this issue too. But my Exchange 2010 wouldn't send\receive any emails after these errors, plus RDP and Hyper-V console gone down. So I had just one way - Turn Off and Start. It's very annoying!!! I'm waiting MS resolve of this trouble asap.

Same here. Any solution?
Tuesday, April 20, 2010 5:21 PM+1 - same problem on each restart

at least I've got some hope. On friday I had the opportunity to talk to an Senior Premier Field Engineer for Exchange who said, that he believes this issue is addressed in SP1 for Exchange Server 2010. He wasn't perfectly sure about it, but I will try to get some more info on that.
Sunday, May 16, 2010 6:58 PMAdd us to the list of folks experiencing this problem, exactly.
Monday, June 14, 2010 1:44 PMI also have the same problem
Monday, June 14, 2010 4:46 PMI got the confirmation through a PFE, that the issue is known and will be fixed in build 14.01.0136.000. So with SP1 for Exchange Server 2010 the problem should be gone.

Event 12025 text: Transport service is disconnecting performance counters with process lifetime from their old process.
This event is still present in Exchange 2010 SP1 but the other one has now gone......
Friday, December 10, 2010 11:49 AM
Is anyone here, who could fix the problem?
Microsoft said: "Warning by design" - Is there a possibility to turn of or to fix that message?

I'm having the same issue. Clean install of Exchange 2010 SP1 UR2, and Windows Server Enterprise 2008 R2 SP1. Currently there is only the default mailbox on this server, and there are no user mailboxes on this system. I'm only getting the "Event 12025 text: Transport service is disconnecting performance counters with process lifetime from their old process." warnings.

Hi everybody, I'm not sure where I found this blog, but it helps to fix the problem :-)
A little bit work, but unloading and reloading the performance counters helped me to fix the problem.
Saturday, March 26, 2011 7:25 PM
Thanks for the hint and link. I've unloaded:
remove-perfcounters –definitionfilename “C:\Program Files\Microsoft\Exchange Server\V14\Bin\perf\AMD64\eseperf.xml”
then reloaded counters:
new-perfcounters –definitionfilename “C:\Program Files\Microsoft\Exchange Server\V14\Bin\perf\AMD64\eseperf.xml”
and restarted the Exchange 2010 (Build 639.21) server, but 15 warning messages with event ID 12027 from MSExchangeTransport source reappeared :(
Any other hints?
Wednesday, December 21, 2011 2:44 PMDid you guys ever solved this. Tried the link above but didn't help me. Running SP1 with latest Update (haven't tried SP2 yet).
Wednesday, December 21, 2011 4:31 PM
For us, Event 12027 stopped occurring after we installed SP1 RU5 or RU6. Since SP2, which we have also installed, is cumulative, it should include fixes from RU5 or RU6.
One instance of Event 12025 still occurs when the MSExchangeTransport service starts. I think this event could be reclassified from a Warning event to an Information event. We ignore it.

We have the error message:
Transport service is disconnecting performance counters with process lifetime from their old process.
also on our Hub Servers. Since we installed SP2 for Exchange 2010 the issue is no longer in place.
