Hi, I have several servers all running the same software that have recently started having trouble. The symptom is that intermittently, usually (but not always) on a POST after a delay of 30 - 60 seconds, my users receive "The page cannot be displayed" error. When they click refresh the correct page is displayed immediately with the correct content. I have inspected the packet data of the request and it seems that the server sends a RST packet directly after the client requests the page. I have searched google for days to no avail. Please help. I think the problem most likely has something to do with Tomcat because I don't receive this error with my mail server, dns, etc. To troubleshoot this problem I have done the following, which have all had no effect: Disabled the firewall (now enabled) Used Apache with a connector Added and changed the "connectionLinger" value in the connector to a few values Updated various other connector properties Replaced the Linksys switch with an unmanaged switch Reinstalled the application Here are the details of my systems: OS: RH ES3 CPU: Dual Xeon with hyperthreading enabled RAM: 2GB Tomcat: 5.0.28 Java: j2sdk1.5.0_06 Thanks, Matt
