Quarantined message * as it caused MailScanner to crash several times

[Richard Mealing]

Hi,

I have searched for a while and I cannot find a solution to my problem. The only reference to this problem was when I reported it back in 2011.

I've been struggling along updating to the latest mailscanner and FreeBSD versions but this problem keeps hitting all of my servers once and a while.



Basically I get a log entry similar to this  -

Jul 17 22:44:40 mailfilter6 sm-mta-in[8204]: r6HLicbY008204: to=<info at somedomain.com>, delay=00:00:01, mailer=esmtp, pri=63196, stat=queued

Jul 17 23:00:53 mailfilter6 MailScanner[14733]: Quarantined message r6HLicbY008204 as it caused MailScanner to crash several times
Jul 17 23:00:53 mailfilter6 MailScanner[14733]: Saved entire message to /var/spool/MailScanner/quarantine/20130717/r6HLicbY008204

It then fails on every subsequent message. To resolve I have to turn off the server and remove all the emails in the queue. If I pass the emails over to another server, say around 6000 emails, that server then has the exact same problem.

I've debugged mailscanner and spamassassin, I don't see any problems with SA, but mailscanner I get the following, still -

Can't call method "CombineReports" on unblessed reference at /usr/local/lib/MailScanner/MailScanner/MessageBatch.pm line 736.



Can anyone help me with this problem? I am using the -U flag, but this doesn't make any odds to the problem.

#!/usr/bin/perl -U -I/usr/local/lib/MailScanner


When I debug mailscanner I move the first problematic message to it's incoming queue and run the debug (I stop mailscanner before this so it's not running as a daemon) and I get no problems with the debug, but when I run it with over 6000 emails in the queue it comes up with the above debug message. I imagine this is a problem with timeout or such, but I'm not sure why it stops processing messages in the first place.

Does anyone have any ideas what I can do to fix this problem?

Thanks,
Rich
