Hello,

Make sure that you have enough RAM space in your system.

Reduce your minimum heap size to 64m, for that you have to change the value of JAVA_OPTS in the $JBOSS_HOME/bin/run.conf file as shown.

JAVA_OPTS="-server -Xms64m -Xmx128m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000
