Hello,
It's a very long story how I got to this answer for our mail servers, but if
you do the following registry change I'll bet a cup of coffee that your
problem goes away and your server has some minor increase in overall
capacity. This change adjusts the size of desktop heaps created by
non-interactive services. The default from Microsoft is 512. After some
research and lots of testing 2048 is our magic number. This will not
actually require more installed RAM on your server, but is mysteriously
helpful.
2. Under the HKEY_LOCAL_MACHINE subtree, go to the following
subkey:
\System\CurrentControlSet\Control\Session Manager\ SubSystems\Windows
The default data for this value may look something like the following (all
on one line):
%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows
SharedSection=1024,3072 Windows=On SubSystemType=Windows
ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3
ServerDll=winsrv:ConServerDllInitialization,2 ProfileControl=Off
MaxRequestThreads=16
You must make the following change to this value:
Scan along the line until you reach the part that defines the SharedSection
values and add ",2048" after the second number. This value should now look
something like the following:
%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows
SharedSection=1024,3072,2048 Windows=On SubSystemType=Windows
ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3
ServerDll=winsrv:ConServerDllInitialization,2 ProfileControl=Off
MaxRequestThreads=16
After making this change, quit Regedt32, and then restart the server.
I am assuming you are running Windows 2000 Server and have not confirmed
this Windows 2003.
Some of the above info is referenced in the following Microsoft article

Let me know how it works for you.
