No!
Which version are you running?
What OS?
What kind of hardware?
How long does it run before needing a reboot?
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.
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.
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.
Hope this is helpful.
