We are seeing a 2008 R2 server running increase its Metafile usage (as indicated via RAMMAP) rapidly from around 1 GB to 8Gb. Is there a way to break down this usage so that it is possible to see what is causing this RAM increase? What are the likely causes for this increase? Thanks

Hi, Can you verify which process takes the high memory usage in Task Manager? Please test the issue in Clean Boot to narrow down the cause. For the detailed steps, please refer to the following Microsoft KB article: How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7 http://support.microsoft.com/kb/929135 If the issue persists, would you please send me more information for analyzing.

zoics, did you find what was causing your issue? I have a WS08R2 that has this same issue. The server is running Hyland Onbase which basically has tons of image files that our users search in IE. If we reboot the server the metafile memory usage goes away; but over time it grows and grows; currently its around 9 of the 12GB the server has. We start having performance issues when it grows to this size. It makes sense that windows is caching the metadata for the files accessed but i need to determine if this is a windows issue or an application issue. Thanks in advance for any help!

Hi, we have the same issue. The link you have posted only discusses the issue, but offers no solutions. Our server, 2008 R2 STD SP1 with all patches up to date, eats up all RAM nightly as a result of TSM backup agent. As indicated by RAMMap Metafile Standby cache grows to almost 8GB, physical RAM size on our physical server. At this point the server becomes very slow and barely usable. We have noticed that resetting NIC clears all this cache. Unfortunately, this is not a permanent solution. Also, during the course of a day, large amount of relatively small files is either copied to or retrieved from this file server by Windows 7 client PCs. This causes Mapped File Standby cache to grow and eat up all FREE memory as listed by Performance monitor. This makes the server unusable too. The same trick with resetting NIC solves the problem. The server has the latest HP Support Pack and firmware installed. Does anyone have a solution to this issue?

We also have a server with Hyland Onbase and I am running into the high Metafile usage as well as high Driver Locked memory usage. I believe the Driver Locked memory usage has something to do with the VM Tools installed on this server. But I am wondering if you ever came to a solution with the high Metafile usage? Thanks for your help.

Has anyone managed to resolve these issues yet? We are having a similar problem. We have a file server that contains somewhere in the region of 6 million files spread across 600k folders and when the full backup runs, you can watch the memory usage go up and up until eventually it just trips up and the process terminates and the backup fails. Is this more likely going to be resolved by throwing more memory at the problem, or will this problem still persist? Currently this is a Windows Server 2008 R2 Standard edition with SP1 installed and it has 12GB of RAM.

I am having the same problem with TSM on Server 2008 R2 doing an image backup. There might be a fix from Microsoft, but it looks like you have to open a support case (which is TOTALLY bunk). They CLAIM the issue was fixed in Server 2008 R2, but we all know that is not true... There is an article on it: http://support.microsoft.com/kb/976618/en-us Which points you to the download for the Microsoft Windows Dynamic Cache Service: http://www.microsoft.com/en-us/download/details.aspx?id=9258 Problem is, it will not work on Server 2008 R2. The article directs people with R2 to open a case. I used the RAMMap utiliy from Sysinternals to clear it out, but that is a manual process...
