Look for the DeadlockDebugger and install that and follow the instructions. Hopefully it can help you debug what Zope is doing when it's not responding but still ticking. Perhaps you've got some dead connections to the database that refuse to timeout. Chris Hoy wrote:
Hi
Several weeks ago I moved one of my machine to a new server and upgraded zope from 2.7 to 2.9 as well as the database from mysql 4.1 to 5.0.38. All seems to be going well expect that on a couple of occasions the zope server has stop repsonding to request. The server is takeing 0% cpu and the only way to get it going again is to re-start zope. I can't see anything in the event.log file or on the machine (the debug info is below)
Can anybody point me in the right direction to try and find out what is happening
