Around 4:00 pm last night, as close as I can tell, I received a few scattered reports that one of my Exchange servers was responding veeeeeeeery slowly. I took a look and didn't immediately see anything wrong -- My Outlook was responding normally. This morining the Helpdesk got flooded with calls about slow response time.
I dug much deeper and didscovered that the disk containing the Information Store was pegged at 100% utilization. Every 25 minutes or so the utilization drops to about 10-20% for 2-3 minutes and then pegs again. I have run a manual virus scan which turned up nothing, Checked the event logs for maintenance processes still running and found nothing, rebooted the server and the utilization returned to 100%, Stopped the event service with no luck, stopped OWA with no luck. This is the first time in 5 years of running Exchange I have had something like this. Exchange 5.5 SP3 Win NT 4.0 SP5 Compaq 3000 Dual 600 MHz processors 512 Mb ram IS disk is raid 5 27 GB 25 GB used Log disk is raid 1 8GB CPU utilization is 15% average during peak usage IS has 493 MB free space after online Defrag. Thanks in advance for your great support.
