[jboss-user] [JBoss Remoting] - EOFExceptions and IOExceptions in remote EJB calls under load

Christian Kölle [https://community.jboss.org/people/chrkoelle] created the discussion "EOFExceptions and IOExceptions in remote EJB calls under load" To view the discussion, visit: https://community.jboss.org/message/800098#800098 -------------------------------------------------------------- Hi I have posted this question in the JBoss 7 forum but didn't get an answer. I hope that somebody in this forum has some idea what's the problem here. We have a web application that ist split up in a frontend and a backend application. The frontend calls EJBs in the backend. This works pretty well but in production we occasionaly we get exceptions at times that we know as high load periods. Both applications run on JBoss 7.1.2 application servers. In the frontend we see something like this: 00:59:10,337 ERROR [org.jboss.remoting.remote.connection] (Remoting "jboss-web-extern" read-1) JBREM000200: Remote connection failed: java.io.IOException: Input overrun 00:59:10,393 ERROR [****] (ajp-/0.0.0.0:8009-130) Cannot perform usecase *** java.lang.reflect.UndeclaredThrowableException         $Proxy75.performUseCase(Unknown Source)          ......

For me it is not clear what this means. Does this have an effect on the users? Is there a problem with our implementation or perhaps the configuration?
