    • CP03
    • CP04


  • In a remote domain and host controller set-up if a patch (CP03/CP04) applied on remote host controller then it fails with an OutOfMemoryError :
patch apply --host=some-host jboss-eap-6.2.3-patch.zip
. . .
13:58:40,478 ERROR [stderr] (domain-mgmt-handler-thread - 1) Exception in thread "domain-mgmt-handler-thread - 1" java.lang.OutOfMemoryError: Java heap space
13:58:40,479 ERROR [stderr] (domain-mgmt-handler-thread - 1)    at java.util.Arrays.copyOf(Arrays.java:2271)
. . .


  • As a work-around, increase the max heap size on the domain controller(s) by temporarily editing HOST_CONTROLLER_JAVA_OPTS in bin/domain.conf. A setting of -Xmx1024m should work.
