[Zope] Re: Pavlos's suggestion: -t 1

[Dr. Ross Lazarus]

I set t -2 yesterday arvo after what seemed like blissful stability with
t -1

crashed this morning under almost zero load - after a 3 hour period of
inactivity, when I opened up the management screen.

sigh...

Houston, we have a serious problem here which seems to go away when we
run a single thread. Unfortunately, a single threaded zope is not much
use to us here....
