Only about 7% free on your primary partition?  Depending on how big your
paging file is, that's not enough free space.  Try and move some stuff
off that drive or consider more/bigger disks.

Subject: Exchange 5.5 IS disk at 100% utilization - HELP!


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.
