Hello,

In my application I invoke external webservices. During performance tests when application is under heavy load I am receiving below exceptions:

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
