Re: [Declude.JunkMail] Imail crashes

Thu, 21 Apr 2005 13:04:21 -0700

I've seen a lot of posts about this over the years on the IMail list. It is likely an IMail issue. The suggestion to turn on "Auto-deny possible hack attempts" in IMail's SMTP Security is one possible fix, and you didn't indicate anything in regard to that suggestion. You might try searching the archives for the IMail list on mail-archive.org for what others have experienced and potentially the fixes. If you have a support agreement with Ipswitch, you might also try that route as they should be familiar with the condition. It seems hit or miss as to who experiences it, but I can't recall ever seeing Queue Manager crash on my box, and the only IMail related crash was POP3 which happened twice after migrating to Windows 2003, but I think that McAfee was the culprit that caused the instability.

Just a few minutes ago the Que manager stopped.
I did restart it fine this time.

What could this be?

Thank you for the reply.

Running 1.82 actually.
Imail monitor is off.

Its a dual Xeon 3.0GHz with 2GB Ram.
Load is pretty low. About a million emails a month.
No evidence of extra load.

I did turn off the auto restart.

Lets see if that makes a change or not...

Thanks,

Turn off the IMail Monitor service and see if things don't become more stable. There have been suggestions that it will try to restart a service that is only overwhelmed but not crashed, and the restarting process can then actually cause it to crash. Windows 2003 services have their own recovery capabilities that should be more stable. I have seen this happen before. It is quite possible that some added load might be pushing your server to the limit, or maybe a piece of content that IMail doesn't like seeing and Declude isn't filtering. I've heard of that happening in the past also. Turn on "Auto-deny possible hack attempts" in IMail's SMTP Security if that isn't already on as this might also be the result of an overflow condition during the SMTP session.

Declude 1.81 has a big flaw in it with the SPAMHEADERS test and you should upgrade to at least 1.82. This shouldn't explain the instability.

You should give some more detail about your server, especially conditions related to load if this continues. There are many of us running 1.82 without issues, and with SP1 my own server seems stable and I have a good deal of volume going through it.

We are crashing like crazy today, quemanager status goes to stop pending.
Can not restart it, have to restart the server.

Imail 8.15 with fix
Declude 1.81
Fprot 3.16b
Windows 2003 Server Standard with Sp1.

Suggestions please....

Sorry about not getting back to anyone – some malcontent set up a winmx server in my network! Anyway the bottom line right now is:

Declude 1.81 - No problems for about a million years

Declude 2.0.6 - Imail crashes for two days

Reinstalled Declude 1.81 - No crashes for 1 day

Installed SP1 with Declude 1.81 - No crashes for ½ day but it seems to run slower

Any thoughts – we are going to let SP1 run through the night. If it still seems slow to access mail we will remove SP1 in the A.M.

Thanks,

Nothing about the service that SP1 installs, but I did I find multiple pages on Microsoft's site about "Application and User Experience", which seems to be their quality and regresssion testing. They indicate that 3rd party vendors should follow:

http://www.microsoft.com/windows/appcompatibility/default.mspx

and

http://www.microsoft.com/windowsserver2003/partners/isvs/appsupp.mspx

this application testing in order to verify that their applications work correctly with their OS. There is also a page that lists 120-plus applications that this "Application and User Experience" team tested with Windows Server 2003 SP1, and produced results (including their own software):

I don't know if this is of any help here, but two new SP1 features
that I don't understand and I fear to some extent are the
"Application Experience Lookup Service" and "Data Execution
Prevention (DEP)". It seems like both might represent overhead to
things like Declude which are called from a command line along
with all of the applications that it calls, and it might not be
wise to run them in such an environment. I haven't tried turning
them off yet, but I was just starting the process of researching
them. The "Application Experience Lookup Service" can be turned
off in Services, and "Data Execution Prevention (DEP)" is
controlled by the boot.ini. I can't find hardly any information on
the "Application Experience Lookup Service", but "Data Execution
Prevention (DEP)" has a KB article about it:

    http://support.microsoft.com/kb/875352

    There is also another level of DCOM security, and this may or may
    not cause issues with .NET stuff. I don't know.

    I haven't tried upping from Declude 1.82 yet as I wanted to apply
    SP1 and make sure that it was workable before introducing
    something else that was new to the environment.

    I'll add our point too. We also are crashing with 2.0.6 (also SP1
    installed). We've put back 1.82 into production. No issues.

We just put SP1 on this morning but have not had a crash since
we went back to 1.81 on Declude.

        Thanks,

        I haven't upgraded jet to v2 but can see the same problems
        with imail since installed win2003 SP1

Haven't seen any crash since removing SP1 but this is not 100%
sure at the moment. I will report it later this week.

Last Friday I finally upgraded from 1.81 to 2.0.6. We
use Declude Pro Anti-Spam and Anti-Virus. On Friday
after the install Imail web messaging crashed several
times. We let the problem go until Monday. On Monday
the problems got worse with numerous crashes of web
messaging. I finally recopied 1.81 and have been crash
free for 2 hours. What is going on with 2.0.6? Do I
need to reconfigure something? Win2003 on a xeon
processor with 2gb memory.

                Thank you,
