I have a big problem with a customers Zope instanse - almost every day it "falls asleep": When you try to access their site it's like no requests get's to the site. I try to stop the instance - and when I start it again I'm told that another process has already locked the database file.
There is a HowTo on "SpinningZope" analysis. It may help you.
Running $ps -ax reveals that their is some stale python processes mathing the PID of the recently stopped Zope instanse ...
I have seen such behaviour in the past. It was caused by network problems. NFS access blocked deep inside the kernel and normal signals did not release the process. I would probably try to use GDB to analyse what the Zope processes are doing when they do no longer respond. Dieter
