Sun Java System Application Server Standard stops responding for no reason
Dear Sun Users and Support.
We ran into an issue that we can't find any cause for. For some reason our Sun Java System Application Server 8.2 Standard stops responding to HTTP calls. Even Admin console can't be invoked. The server by itself appears to be running according to the Windows Services window.
It happens very rarely but once it happens the server needs to be restarted.
There are no logs in the log files.
This happens to multiple Sun Servers at the same time (As if some kind of timer shuts them off).
The servers run on Windows Server 2003.
Any help would be greatly appreciated.
These servers are in the production environment and have expected uptime of 99.9%.
Thank you.

This has happened to us a couple of times and it was caused by Windows running out of TCP/IP connections. Next time it happens do a "netstat -an" to see if you have an extremely large amount of connections in time-wait state.
If you do this is probably the culprit and I'm sorry to say that I don't know of a cure. From what I've heard (objection your honour, hearsay!) this is caused by bugs in Windows TCP/IP stack.
If you require a 99.9% uptime you should perhaps consider switching to Linux or Unix. I know, easier said than done!
Hope this helps,
Gunnar

Thank you for your reply. The JVM version we use is 1.5.
