A issue has been confirmed recently by Microsoft that is impacting users of the Windows 7 client operating system and users of the Windows Server 2008 R2 server operating systems even if the latest service pack and updates are installed.
Some customers running those operating system versions have reported that their systems stop responding randomly.
Microsoft has analyzed the issue and discovered that it will typically occur when the memory usage is high and when the Windows memory manager performs "frequent paging in and paging out actions".
The cause is a deadlock situation in the Microsoft Filesystem Filter Manager (Fltmgr.sys).
Microsoft has released a hotfix and instructions on how to pinpoint the random freezes and lock-ups of the operating system.
The hotfix is available for download at the Microsoft Support website. Users who want to download the hotfix need to access the terms of service and fill out information on the Hotfix Request site including their email address before they can download the program to their computer system.
Microsoft sends a download link of hotfix to the email address entered in the form on the hotfix request page. This in itself is a rather complicated process; A simple download link would make it a lot easier for users to download the fix from Microsoft.
It should be noted that only users who experience freezes and responding issues should download and use the hotfix to resolve those issues on their operating system. The hotfix will eventually be included in one of the scheduled patches for the operating system.
From what I can tell, the hotfix replaces the old version of Fltmgr.sys with a new version that does not cause the issue on the operating system anymore. The fix is available for 32-bit, 64-bit and IA-64 Windows 7 and Windows Server 2008 R2 operating systems.
I have to admit that I did never experience related issue so far and I'm running Windows 7 since the beta on my main system. Did you ever experience freezes? Let me know in the comments.
