[Mailman-Users] odd errors with mailman

[Dan Mick]

1) qrunner won't run with those lockfiles there, so they should
be gone before you try again.

2) if you have the cron entry commented, qrunner won't run at all
unless you run it by hand.

I assume you know these things, but it never hurts.

3) Any theories for how the lock files got bogus dates?  Did you
have NTP problems, or did someone reset the date wrongly on this machine,
or something?  Is TZ a suspect (different for mailman vs. other processes
or something?)

4) what do the "ignored" log entries show up in?  One of Mailman's logs,
or your MTA's?

5) the logs/error excerpt doesn't actually seem to show the error,
which is odd.  Could you mail me the whole file privately so I can
look at it?

6) can you try running qrunner under some syscall-tracing utility
(Solaris: truss, BSD: ktrace, Linux: strace) to see where it's stopping?
