--- Comment #32 from Chris <cpollock at embarqmail.com> ---
Things have apparently changed for some reason. Firstly I'll call this a 'hang'
instead of a 'lockup' because all background processes such as Fetchmail,
Procmail, Postfix and others continue running and doing what they're supposed
to do. Since the 17th of January I've experienced approximately ten more of
these system 'hangs' and not a single one have the 'Hangcheck...' error in the
syslog anywhere. In fact I've had two in the past 24hrs, one this morning when
I first went to access the computer and the 2nd about 15 minutes ago. Can
anyone give me an idea of where to proceed from here to try and find the
problem. I can say that the 'hangs' seem to happen about every 2.5 - 3 days.
