amavisd crash

[vinx]

Hello everyone.

My Debian Sarge Mail Server with postfix+mysql+courier+blablabla is working pretty well exept that sometimes amavisd crashes.

this is from /var/log/mail.log:

Mar 25 04:23:49 mail amavis[28483]: Net::Server: 2006/03/25-04:23:49 Server clos
ing!
Mar 25 04:23:49 mail amavis[6680]: (06680-03) tempdir being removed: /var/lib/am
avis/amavis-20060324T161921-06680

avis/amavis-20060324T150854-06587

this is from crontab:

23 4 */2 * * /usr/local/sbin/sa_rules_update.sh &> /dev/null

I think somethimes, during sa_rules_update.sh job, amavisd crashes.

Any idea?

Regards,
Vince

Does amavisd stop totally, or does it continue to work?
I can imagine that this is just a server process that stops and that another server process is started. amavisd runs several server processes at the same time.

amavisd stop totally, all email received are deferred until I manually start it with /etc/init.d/amavis restart command.

You could try to update the Net::Server Perl module. Maybe it helps.

Excuse my ignorance, but, how to do that?

[falko]

Run
perl -MCPAN -e shell
On the Perl shell, you do this:
install Net::DNS
Afterwards, type q to leave the Perl shell.

Ok, I did it, but now I have another problem!.

Please check again all the configuration files and compare them to the ones from the tutorial (also check their format (spaces, etc.)).

the problem above happened just once, but amavisd crash still happens.

what about to put /etc/init.d/amavis restart in crontab everyday?

[falko]

That wouldn't be very reliable.
You could install monit to check the availability of amavisd (and let it restart it if it isn't running): http://www.tildeslash.com/monit/doc/
