Strange CORBA RMi exception org.omg.CORBA.MARSHAL: Error sending fragment
we have a heavy load EJB application running on WebSphere 6.1. Lately, we've been having a lot of connection problems, Client application (standalone java app) gets the exception below and the request is not completed. The server is up and running, pings are fine and other clients can connect and send requests, so it is not a connection issue. We couldn't reproduce this problem on our test servers. Could anyone please help us figure out what's causing this problem? Is there some WebSphere config param we're missing? 

Thank you.
