[Mailman-Users] locks

[Brian Haines]

I am very new to all of this including using Mailman, Linux, Sendmail,
etc...

I have Mialman 2.0.13-1 on Red Hat Linux using Sendmail as the MTA.

It has worked a few times, but right now when I send my announcement it
fails. Why I don't know but here are some things I can see:

There are files in the /var/mailman/locks folder called qrunner.lock and
qrunner.lock.www.domain.name. When I delete them and refresh the list I can
briefly see listname.lock and listname.lock.www.domain.name and the above,
but the listname items disappear after a few minutes.

Here is the TOP output. I don't know what else to look for. Nothing is going
out anywhere.

xxx.xxx.xxx.xxx is our IP address. I mention this because we are using
something else I am unfamiliar with called IPTables to assign the outgoing
mail to one of our other IP addresses like so:

iptables -t nat -A POSTROUTING -p tcp --dport 25 -j SNAT --to-source
xxx.xxx.xxx.xxx

I don't even know enough to know if xxx.xxx.xxx.xxx in TOP should be our IP
or the receiving server IP.

I do appreciate any hep at all.
