[jboss-user] [Performance Tuning] - getting the folowing NPE and ServletException on Jboss under

[kenety]

Hi, 

I'm getting the folowing NPE and ServletException on the server.log when sending HTTP requests to JBoss under load for each and every request (this happens after a while during the load testing). Do you have an idea why? Is there any configuration that I'm missing? Thanks!
