dbmail/maintenance causing "manage_stop_children" General stop requested on imap, pop3, & lmtp

It's a postgres backend 8.3.7. dbmail 2.2.11 on Fedora 10.

Is this actually related??

Thanks!

You should tell us that. Running dbmail-util will never stop any
daemons. My guess is you have some kind of guardian process running that
kicks in here for some reason.

And you should not run dbmail-util -ay if you have auto-vacuum enabled.

Avoid the -c flag in that case, and run:

dbmail-util -tubpdsy

Aha! I was a little confused at first, because I didn't even know what dbmail-util was -- but I found the culprit. The Fedora RPM creates a file /etc/cron.daily/dbmail which contains the following shell script:

#!/bin/sh
LOGFILE=/var/log/dbmail.log
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/lib/dbmail
echo "" >> $LOGFILE
date >> $LOGFILE
dbmail-util -c -t -u -p -d -y 2>&1 >> $LOGFILE


Per your suggestion, I've changed the last line to exclude the "-c".

Thanks Paul!

Would that have to be
dbmail-util -c -t -u -p -d -y >> $LOGFILE 2>&1
? I've thought that if you first do 2>&1, it reconnects stderr to
stdout, and later you change stdout to $LOGFILE, but then stderr stays
on the previous value (which is normal output).

If I'm right, that's a bug and should be reported to Fedora.
