Hello All, Zope stops responding to requests, however when I check the zope process I see seven threads plus watchdog thread. ( ps auxww | grep z2 ). I am not sure why it stops responding. Actions taken to diagnose the problem: 1) I added the -M option and started logging to the debug file. 2) I am using the requestprofiler.py script to see which request in particular causes the problem (hangs). Everytime the request seems to be different. I make the same request and it runs without hanging zope. So I cannot duplicate the problem. I backup the Zodb every night and I have modified the stop script. I first kill the watchdog pid then I do a wget on http://$ZOPE_AUTH@$ZOPE_HOSTNAME:$ZSERVER_PORT/Control_Panel/manage_shutdown. Could this method of stopping zope be the cause? Also there are no core dumps. System Info RedHat 7.2 Zope 2.5.0 Python 2.1.3 Thanks Ahsan Imam
