    Redeploys cause OutofMemory Error

    Gurinder Randhawa Newbie

      We are deploying 5-8 modules EAR files on single JBoss EAP 7 Beta instance running  Java 8. After a few redeployments using CLI (command line interface) JBoss runs out of memory, the process does not always die.  We are running JBoss in a docker container and find docker process cannot be stopped either due to OOME. We are expecting JVM memory of previous deployment to be reclaimed by GC but it does not. Has anyone experienced similar issue?
