Hello,
Dell Poweredge 2800
3GB ram
2- 3GHZ Xeon processors with hyperthreading on
8- 300GB SCSI HDD's in raid 5 configuration
SBS 2003 with Exchange
Trend C/S/M Security for SBS
Also used as a file server
I am having the following issue.
About once a week my server slows down to a crawl. This can happen even when the server is not being heavily utilized. The problem is fixed by either rebooting the server or waiting about an hour or so and it clears up. Here's a couple of things I have found.
Performance monitor shows pages/sec and avg. disk queue length are constantly maxed on the graph.
The disk activity lights on the server flash a repeating sequence over and over. For example (disk 4, disks 1&2, disk 8, disks 6&7, disks 3&5)
From what I can see there are 2 processes that run when there is an issue and don't run when all is normal. dbserver.exe and dcstore32.exe
Application Event viewer shows 2 or more of the following Warnings every time.
