[jboss-jira] [JBoss JIRA] (WFLY-4881) Cli calls leak memory in Host Controller when reading children names in domain mode

[Michael Noack (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-4881?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13088786#comment-13088786 ] 

Michael Noack commented on WFLY-4881:
-------------------------------------

So I ran a stress test of 4 days doing as many cli operations as the VM would support per minute (roughly a hundred) on plain wildfly-9.0.0.Final using the workaround. The JVMs heap is still looking healthy. So it looks like the memory leak is really limited to the issue identified by Brian Stansberry.

Looking forward to repeat the test without the workaround once 10.0.0.Beta1 has been released.

> Calling the cli using the command:
> {{jboss-cli.sh --connect  --user="myuser" --password="mypassword" --command=":read-children-names(child-type=host)"}}
> leaks memory to old gen. Eventually the host controller goes OOM if called to often.
