Hello I had thread blocking in my installation du to using the sendmail tag with invalid recipient(empty). I solved this and now my 3 'production' zope installations works well since months.

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?
