Exchange 2010sp1. Several times a day, a warning event ID 906 source ESE


  • Hello.

    Installed on the server exchange 2010sp1. Has been working for about a year. Two months ago, on a regular basis once or twice a day in the log started to appear warning


    Log Name:      Application
    Source:        ESE
    Date:          02.11.2010 21:11:46
    Event ID:      906
    Task Category: Performance
    Level:         Warning

    Information Store (2920) 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 45629 buffers (or 36%) in the last 39035 seconds.
    Current Total Percent Resident: 50% (80316 of 157642 buffers)


    In what may be the problem?

    The size of the mail database of about 30 GB. 50 mailboxes.

    The server is a 2 cpu xeon 5530 on 4 cores. 12 GB of memory ddr3 (though 3 GB taken away by two virtual machines vmware). Disk array from 4 drives sas 147 gb in raid 10 (adaptec 5805).

    The server keeps the role of exchange Hub Transport, Client Access, Mailbox.

    Is that server does not have enough performance to services 50 mailboxes?
