Hello,
In my application I invoke external webservices. During performance tests when application is under heavy load I am receiving below exceptions:
Caused by: SystemUnavailableException_Exception: unknown exception caught

This looks like issue with deserialization however I see it only during perfomance tests for random requests.
I am using jboss 4.2.2 with JBossWS 3.0.5.
Could you give me any hint what I should do to handle those exceptions?
Thanks,
Marcin
