Start Zope with the z2.py command line option "-M var/detailed.log" e.g. ./start -M var/detailed.log Detailed.log will contain a transcript of all requests processed by the server and their responses. If you see a method call without "end of request", that's probably the point that the thread is leaking. ----- Original Message ----- From: "Jay, Dylan" <djay@avaya.com> To: "'Chris McDonough'" <chrism@digicool.com> Sent: Monday, December 18, 2000 7:26 PM Subject: RE: [Zope-dev] Fault tolerance and thread-loss

How can I do that when I can't get into the interface because there are no threads left? How do you suggest I debug it?

No. You shouldn't be leaking threads. Can you trace the thread leakage down to a single Product?

I'm finding that my installation is blocking all requests after awhile. By best guess would be that threads are being used and somehow becoming permanently blocked. When all 4 are gone then the server is useless and has to be restarted.

Seems to me this is a real problem for fault tolerance. Perhaps a monitor should be run on a separate thread that starts aborting transactions when they have been running too long and there are few remaining threads.

Does this exist already?
