Memory leaks in Server 2003

[JaneHyson]

Has anyone any experience of sorting out a memory leak in Server 2003?

Kernel or userspace leaks?

What memory leak?

How do you know you have a memory leak? Have you tried the Performance and Monitoring tool in Server 2003 to check your virtual memory use?

On 32-bit systems VM is limited to 4GB. If you have a large amount of RAM on your server (1-2GB) VM might become exhausted before a shortage of physical memory takes place (I've seen this once in fact). When that memory is depleted and is never returned- that's when you get a "leak".

You might find that you either have an errant process not releasing memory to the system gracefully (in which case your application has a bug) or that you need more physical RAM to cope with the tasks the system is required to complete each day. Either way, got Administrative Tools > Performance Monitor and watch what happens with your memory allocation and VM.

Let us know.

This is definitely a memory leak, it occurs overnight I suspect it may caused by Veritas backup software. Once in a while we come in and find this particular server has frozen up, there is plenty of RAM, it is definitely caused by a process not releasing memory. I just wondered if anyone had experience of solving the problem and which counters they set on Performance monitor

@JaneHyson: Have you checked for viruses and spurious processes? Also maybe check that you are fully patched - Veritas may have have a fix.

Are you using the new version of Sophos?

lol @ Geoff

Also Jane, if the actual memory modules have just been added to the server, then you might want to check them too just wanted to add that.

Is there anything in the Event Log Viewer indicating anything to why it froze etc?

Cheers and please let us know how you get on
