java.net.SocketException

[Anselm Paulinus]

Hi All:

I have an application which sometimes throw the exception java.net.SocketException

If any body has an idea of what the exception is, please let me know

The whole exception stack trace is shown below, It happens so irregularly that I can not pinpoint what causes it to happen.

[11:09:21,402,AbstractEngine] Exception during post-request cleanup.
