livecomm.exe using very high CPU and I/O resources RRS feed

  • Question

  • Ever since the Windows 8.1Pro GA rollup update, livecomm.exe has started taking a LOT of CPU and I/O resources on my system. Enough to choke every other app and overall responsiveness.

    A quick look through the SysInternals Process Explorer (screenshot below) revealed that it is taking anywhere between 75% to 100% CPU and around 40 MB/s to 80 MB/s disk I/O (it has read about 200 GB of I/O data since the last two hours alone).

    I have three emails account set to sync. One is the default Hotmail / Outlook account I use to sign in into Windows. The other two are Google Apps account on my work domains set using IMAP for instant push.

    All three accounts are set for instant push in the Mail app setting and only keep data for the past 2 weeks. The Hotmail / Outlook account also syncs Contacts and Calendar as well as one of the Gmail accounts.

    I've been trying to figure out why is it taking so much system resources but haven't found anything solid apart from the fact that it started right after the recent GA update rolled out.

    I recently did a clean install of Windows 8.1 Professional from MSDN and updated to the GA build when the updates were released through Windows Update.

    My system is DELL Vostro 3300 with a Core i3 380M CPU, and 8GB DDR3 memory along with a 2.5" 320 GB Seagate 7200 RPM hard drive.

    If anyone else is having a similar problem, or have a solution, please share.

    I hope this bug gets resolved soon.

  • Install the WPT (http://social.technet.microsoft.com/wiki/contents/articles/4847.install-the-windows-performance-toolkit-wpt.aspx , open a cmd prompt with admin rights and run this command for 60s:

    xperf -on latency+FILENAME+FILE_IO+FILE_IO_INIT -stackwalk profile -buffersize 1024 -MaxFile 512 -FileMode Circular && timeout -1 && xperf -d cpuusage.etl

  • after upgrade to 8.1 on an old dell inpiron 6400 i had a problem with livecomm using 100% disk resources and about 1mbits network chatter to microsoft  ip address as shown by performance monitor even after leaving machine running for 24 hours

    unistalled mail from apps store then reinstalled mail app, after mail had resynched disk activity and network chatter now get to zero a few minutes after boot up

    on a faster quad core machine disk activity was also high and was reduced to zero after reinstall of mail app

    on both machines after reinstall of mail app livecomm would show up in perf monitor as suspended five minutes after boot up but before reinstall livecomm would be constantly active

    after upgrade on a third machine livecomm went into suspend without reinstall of mail app

    on all machines after upgrade there is a  lot of system activity for hours but it should go down to virtually zero

  • I ran xperf like you suggested and here is the result: http://sdrv.ms/184ZLnO

  • the Mail app does some hash checking/calculation. And this causes the high CPU usage for you:

  • I'm assuming this is for downloaded email only. Why does it have to constantly do computations on downloaded email? In the past hour, livecomm.exe has read almost 200GB of data from the disk.

    I'm assuming this behavior is abnormal, because it is causing my CPU to heat up and quickly drains the battery. Any way to address this problem?

  • I have no idea why the app is doing this.  Phone the MS support if you need deeper analyzing of the issue.
