Since a few weeks we have a major problem at a customers site. Their Windows 2000 server (with ata, raid 1) and Exchange 2000 and SQL Server is acting strange. Last days almost every 24 hours many services stops with the error "service not responding for x milliseconds". Most of the times their is a message on the console "low on virtual memory".
Seems like a hardware or software problem?
Someone knows a GOOD process monitor which can monitor and graph all memory and CPU usage of all processes which I can review after a "hang" of all important services like exchange services, IIS service and so on?
We have tried all windows updates en service packs, memory hardware tests (OK), checkdisks....
Could it be a virus? Updated Symantec is installed and active.
Could it be a memory leak of a buggy piece of software?
Someone has ideas? We are running out of good ideas know and the problems seems to be more worse every day.
Thank you all for your reply!
