We have been chasing a problem with our Zope server. Comments from others here on the mailing list have given me the impression that others might be facing the same quandry.
Basically, the problem is that Zope intermittently "hangs".
[detailed descriptions snipped] One thing that I've often find helpful for debugging (in general, not that I've had to do it for Zope yet) is to run strace/truss against your Zope process, then try to make it hang. If you can get it to hang, See what the last system call made was, which might give you an idea of where the hang is occurring. Since you say Zope isn't 'spinning', it's likely that it's blocked in a system call that isn't returning for some reason. The above procedure might help track it down. To make things simpler, you might want to crank the number of server threads down to 1 while you're debugging, though this might eliminate or mask the hang problem. -Doug -- Doug McNaught doug@mcnaught.org http://www.mcnaught.org/~doug
