Hi,
Even though I am running an Imail server for a bachelor level education with about 2500 active mailboxes and about 15.000 mails per day, I still have Declude set to max 150 THREADS. That is plenty to get the mail delivered in time. Declude itself can handle a lot more and using the build in Sniffer helps keeping the max heap problem down, but I have never found a good reason the increase the THREAD count. As a matter of fact I have had it even lower in the past and still mail was delivered quickly enough for users never to notice it.

What’s the cure? Drop the number of threads in declude.cfg? I haven’t looked at it yet to see what I have.

Eventually there were too many command line processes using up too much heap… Some of us were using the old command-line sniffer and 2 or 3 anti-virus command line tools, and invURIBL and various other – each one chipping away at the heap.

After reading all of those, and everything they link to, I have a better idea of what’s happening. What Declude originally called the “mystery heap” is apparently the desktop heap, which had a system wide limit of 48 mb (Win2k and Win2k3), allocated between interactive and non-interactive desktops. Presumably, too many processes are launched, exhausting this heap. Setting a smaller value for the per-process allocation (512 kb by default) should allow more processes to run. So all of this makes sense but doesn’t explain why my server should have this problem. My business is so small any more than I could imagine using my smart phone to run the mail server. If it’s the smtp32.exe process causing the crash, then that would imply to me that I’ve got a lot of outbound messages all at once. I just don’t see how this could happen. I’m guessing that we’ve got no more than a couple hundred mailboxes spread over 30 domains, and no lists larger than 200. So how do I find out where all this outbound stuff is coming from? And is there a setting I could use to limit the number of outbound messages sent (or processed) at one time? Any suggestions are appreciated. Thanks, Ben P.S. I wonder what would happen if I moved my software (Imail 2006.23) to a Win 7 PC or a Windows 2010 server? Just thinking out loud.

IIRC, this is the "mystery heap" problem and solving it will mostly have to do with the setting you're using. http://kb.imailserver.com/cgi-bin/imail.cfg/php/enduser/std_adp.php?p_faqid=686 There is a particular chunk of memory that runs out if too many applications/processes are started at once as children of other processes. In your case, for example, too many concurrent instances of SMTP32.exe along with a number of other factors. If I'm guessing correctly, you could suddenly experience this problem due to allowing enough SMTP32 processes (usually controlled by the number of processing threads you allow) and also having enough mail running through your system to exhaust the mystery heap. This search might help you find what you're looking for in previous discussions.
