Re: Qmail stops working

[Doug Lumpkin]

The first time it hung I just killed everything related to qmail and reran
my rc.qmail file with all my boot up scripts... assuming it was just a
fluke... The second time I had someone testing a web-based email form,
so I really didn't have time to experiment with it so I just:
killall qmail-send
killall qmail-smtp
Then restarted with:
csh -cf '/var/qmail/rc &'
/usr/local/bin/tcpserver -R -x/etc/tcp.smtp.cdb -c100 -u502 -g500
0 smtp \
/var/qmail/bin/qmail-smtpd &
It's running on a Redhat 6.0 box.  It hasn't happened again thankfully,
but it's not a production server and has a very small load... What would
be a recommended procedure for diagnosing the exact problem the next time
it occurs?

Doug,
This is a stumper. The lack of responses means "I don't know what's
going
on here. I'm not going to speculate!"
There is (most likely!!!) an obvious solution, but it's not apparent
to me.
Exactly what OS are you running? How often does the hang occur? When
the
hang occurs, can you kill -ALRM qmail-send or kill -TERM qmail-send?
(You
said you killed it, right? kill -9 or what?) What happens if you kill
-9
qmail-smtpd instead of qmail-send?
