8 years ago Thank you for your prompt answer. We are using JDK 1.7.0_67 As per your instructions I have added the following to teh Gerrit container configuration:
-XX:PermSize=512m -XX:MaxPermSize=1g -XX:+UseConcMarkSweepGC -XX:+CMSPermGenSweepingEnabled -XX:+CMSClassUnloadingEnabledAnd here are all the data of that Java process:
-bash-4.1$ ps -ef | grep Gerrit
