Qmail always hanging

[baravalle]

Hi,
I have a severe probleme with qmail. All the rest of the server is working fine, but qmail is hanging continuosly, almost every two weeks.

I have already disabled the watchdog, after reading in some forum that it might be causing problems.

When qmail hangs, no messages are received. Restarting the service (Service qmail restart) looks like it's not enought to solve the problem, and I typically have to reboot the server, which I don't fancy at all.

Any suggestions?

Andres

PS: I'm using psa-qmail 1.03

You should verify xinetd is running using:

# ps xa |grep xinetd
24917 ? S 0:59 xinetd -stayalive -pidfile /var/run/xinetd.pid

Remote inbound messages are processed via a service registered with xinetd. Restarting qmail will not fix this problem, you can try:

service xinetd restart

The next time it happens and see if that gets it running without a reboot. From there you need to investigate the system logs, /var/log/messages, /var/log/secure, etc.. and see if there is a problem.
