I should add that in looking through my spool folder, I found a *lot* of
tmp*.tmp files, all generated by Armresearch for Sniffer and going way back.
Does this mean I have something misconfigured that these files are being left
over?

Hi,
I just looked in my declude.cfg and found these as the only non-commented
lines:
THREADS 15
WAITFORMAIL 5000
INVITEFIX ON
So it appears I've got 15 threads going. Unless there is some sort of
multiplier going? What happens if my thread count is too small?
Thanks,
Ben

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.
Yours sincerely,

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

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).
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.

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.

Hi,

I recall a while back about errors where you get Error #0xC0000142 (The
application failed to initialize) for smtp32.exe, somehow related to Declude.Â
We started getting these recently for no particular reason that I can think
of. Is there a setting in Declude that helps with this?
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.
Hope this helps,
