Which version are you running? 8.2 HF1
What OS? Win2K SP4
What kind of hardware? Dell How long does it run before needing a reboot? not consistent but ram usage grows above 100 MB's in about 2 hrs
for 8.2 you should see memory between 6 and 20 mb for smaller installs but it can grow to 60 - 120 mb for a very very active server where many users are sending very large attachments. But the mem usage should drop back down to between 10 and 20 mb during low usage times.
memory never drops down
BTW, is there a 'nobody' alias on one of your domains? Or do you have a lot of mail going to one mailbox? This could cause temporary spikes in mem usage if that account is receiving mail with a lot of attachments.
only on our domain
Another issue that I have seen behavior like that in testing 8.2 is the spool drive needing a chkdisk to clean up bad indexes which can be caused by killing a process while it is creating or deleting a file. The issue is that if the service cannot create the spool files the threads will block trying to do that and you will see memory grow, the thread count grow beyond your Max setting (default 60) and the server once all the worker threads are blocked, does not do anything until you kill it. But killing it does not solve the problem, running chkdsk /r does in this case. Defragging is good and should be done often but does not address this particular issue.
