Severe Exchange 2003 performance degradation
Posted on 2011-03-11
Hello - we are experiencing performance problems with our Exchange Outlook users, where it takes a very long time to retrieve data from Exchange. We hace a single Exchange 2003 Server with about 75 users on it. The evbent viewer application log shows many 510 errors like this one:
Information Store (6324) First Storage Group: A request to write to the file "C:\Exchsrvr\mdbdata\priv1.edb" at offset 7658602496 (0x00000001c87d0000) for 8192 (0x00002000) bytes succeeded, but took an abnormally long time (138 seconds) to be serviced by the OS. In addition, 113 other I/O requests to this file have also taken an abnormally long time to be serviced since the last message regarding this problem was posted 50 seconds ago. This problem is likely due to faulty hardware.
We are planning to bring the server down to do some hardware diagnostics, but are wondering if anyone else has experienced this type of issue and found the cause to be something other than the hardware?
