Re: [Declude.JunkMail] error 0xC0000142 smtp.exe
HI Pete, Thanks for the links. 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.

And is there a setting I could use to limit the number of outbound messages sent (or processed) at one time? The trick is, it's not controlled by outbound messages, but inbound messages. The way IMail works is to accept all incoming connections (essentially) and store the messages in the spool. Then it calls it's delivery agent (SMTP32) to get those messages where they need to go. When a message processing system like a mail filter wants to hook into IMail it (or one of it's components) takes the place of SMTP32, processes the message for itself, and then calls SMTP32 itself to continue the chain of processing. (There are exceptions, of course and the above is oversimplified). What all of that means is that the number of times SMTP32 is called is partially controlled by the number of messages you are receiving -- and any publicly accessible MTA is subject to spam storms that can include large numbers of messages. If your software is configured to allow too many instances of SMTP32 then a sizable spam storm will trigger the mystery heap problem. The solution generally is to reduce the number of processing threads you allow. Since your system is small (as you say) this shouldn't be a problem and should resolve the problem.

I had encountered the problem when I introduced another Declude add-on to the mix (e.g., another command line program that Declude was launching).

RE: [Declude.JunkMail] error 0xC0000142 smtp.exe
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.

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?

That is plenty to get the mail delivered in time. Over the years I have determined that you can have a very high inbound throughput on a very small number of threads and in fact that this strategy significantly improves overall performance by reducing overhead. All of the local deliveries you have will be constrained mostly by the underlying file system, so if most of your deliveries are local (inbound traffic) you can set the number of threads very small indeed (2x Cores works as a starting point). You only need a larger number of threads when sending mail out because each thread may need to wait a significant amount of time for the outbound process to start and finish.

Re: [Declude.JunkMail] error 0xC0000142 smtp.exe
No, that's typical. We have a script scheduled to delete them every day. It seems the sniffer script doesn't always delete them... probably Declude still has a lock on the file, so it can be read, but not changed or deleted. We monitor our spool and overflow directories, and when thresholds (by file count) are met we're alerted. Monitoring like this tell you if there is a problem so you can resolve it before your customers notice a problem.
