Hi all Managed to stress the server with 500 concurrent users !! Error message is attached. I would like to understand if I need to go for some ZEO based configuration. At this moment the load will not be as much as this simulated situation. In future (3-6 months) I expect the load to increase. Better start preparing for such situation Regards, Chetan ---------------------------------------------------------------- 2002-08-17T14:22:45 ERROR(200) ZServer uncaptured python exception, closing channel <ZServer.HTTPServer.zhttp_channel connected 192.168.2.47:51059 at 0x8b7de5c channel#: 6685 requests:> (socket.error:(104, 'Connection reset by peer') [/home1/sepg/Src/ZServer/medusa/asynchat.py|initiate_send|213] [/home1/sepg/Src/ZServer/medusa/http_server.py|send|414] [/home1/sepg/Src/ZServer/medusa/asyncore.py|send|338]) ------ 2002-08-17T14:22:45 ERROR(200) ZServer uncaptured python exception, closing channel <ZServer.HTTPServer.zhttp_channel connected 192.168.2.47:51469 at 0x8ef1514 channel#: 6683 requests:> (socket.error:(104, 'Connection reset by peer') [/home1/sepg/Src/ZServer/medusa/asynchat.py|initiate_send|213] [/home1/sepg/Src/ZServer/medusa/http_server.py|send|414] [/home1/sepg/Src/ZServer/medusa/asyncore.py|send|338]) ------ 2002-08-17T14:22:50 ERROR(200) ZServer uncaptured python exception, closing channel <ZServer.HTTPServer.zhttp_channel connected 192.168.2.47:51344 at 0x8c9e21c channel#: 6878 requests:> (socket.error:(4, 'Interrupted system call') [/home1/sepg/Src/ZServer/medusa/asynchat.py|handle_read|82] [/home1/sepg/Src/ZServer/medusa/http_server.py|recv|420] [/home1/sepg/Src/ZServer/medusa/asyncore.py|recv|357]) -------------------------------------------------------------------
What operating system are you running on? These don't look like Zope errors as much as problems with the clients shutting connections to Zope... cheers, Chris Chetan Kumar wrote:

It should catch this exception and silently retry... File a bug report to <http://Collector.zope.org/Zope>.
