Information Store (####) A significant portion of the database buffer cache has been written out to the system paging file.

    Question

  • Question: I have a Windows 2008 R2 w/ Exch 2010 that was migrated from an SBS 2003 server. The migration was successful. Occasionally, in the event viewer, the msg below shows up as a warning. I did a search on google and came up with one link of an administrator getting the same msg. His question was not answered. Any help will be appreciated.

    Btw, there is no SQL Server installed.

    Information Store (2304) A significant portion of the database buffer cache has been written out to the system paging file.  This may result in severe performance degradation.
    See help link for complete details of possible causes.
    Resident cache has fallen by 6999 buffers (or 21%) in the last ? seconds.
    Current Total Percent Resident: 78% (25657 of 32686 buffers)
    Event ID: 906 (ESE)

  • It is newly set up ProLiant DL380 G6 w/ 4gb of ram. It is not getting heavy usage. The msg pops up every once in a while

    Hiya,

    The minimum supported RAM for a multi role server is 8GB RAM. In a single CPU DL380 G6 you should be looking at 9GB, and a dual CPU model 12GB, for an optimal configuration. See the HP DDR3 Memory Configuration tool for more info - this should also tell you what RAM to buy. Also, if you haven't already, make sure your pagefile is set to the RAM size + 100MB

  • At that point in time another process started consuming a lot of memory quickly. So much memory in fact that the ese database that store uses, couldn't flush it's buffer to disk faster than it was getting paged out to the page file.

    If this starts to happen regularly you need to find out which process is consuming so much memory and either find a way to throttle it, or get more memory for the machine.

  • Just to add to this - how much memory does the server have? Does it meet the requirements outlined here , for example?

  • Install sysinternal monitor and explorer to help you find the culprit, or try upgrade the server memory.
