[Zope] 2.2/OpenBSD2.7 runaway

[Brian Livingston]

Zope/Unix newbie here, so please be gentle. Apologies in advance if 
this is the wrong list for this question.

I was having fun with Zope 2.1.6 on a LinuxPPC machine, then moved it 
over to a Zope 2.2, AMD-K6-2 box running OpenBSD 2.7. It ran fine for 
a week, then not-so-fine. Watching TOP, the Zope/Python process is 
consuming ALL available cpu time, rendering the machine completely 
non-resposive.

Python 1.5.2 and Zope 2.2.0 were compiled from source. OpenBSD kernel 
was compiled with maxusers = 128

I get the feeling that this is one of those "oh, you forgot to flick 
that bit" things. I just can't find the right bit to flick! Any 
advice is welcome!
