Hi all, I need some help here - over the past few days two different Zope servers have gone into the 'hanging' state, where they don't reply to further requests. When the first event happened I didn't take a 'top', today, I've managed to get one. The process causing the problem is 12482. From previous messages, I believe that the python CPU can go up to 100%, obviously this isn't happening here. This happened when I asked the Zope server to make a MySQL query. The MySQL server is running fine and I can get to it from a command line interface. Both servers are Zope 2.1.2 source distributions running under Solaris 5.6 This server is running three different Zope sites using Apache as the backend (ie I'm using pcgi to get to my servers). I can't get to it using the pcgi route (ie a ReWrite Rule from Apache), nor from the ZServer incarnation of the server. I also can't get to it from the monitor connection (telnet localhost 8099). I can't let this situation continue as these are live sites. I need to restart the server whenever this happens.
