Deployment files are not purged in EAP 6 domain mode with stopped servers.

Issue

• We are using EAP 6.3.3.GA . When removing a deployment from a stopped AS, it is correctly removed from the meta-data but the files remain inside $JBOSS_HOME/domain/servers/SERVERNAME/data/content. They are not purged on server start. When done with the AS up, the files are correctly purged. This is of course a workable workaround, but we would prefer to avoid it. Is there a mean to automatically purge these files?
• In our JBoss EAP 6.2.4 servers we are having many directories under $JBOSS_HOME/domain/servers/$ServerName/data/content/ which are not getting cleaned up on its own. It supposed to be removed soon after deployment/undeployment in the JBoss server.
• We have an Issue on a server installed JBoss EAP 6.1. There are a lot of files and directories under the /data/content/ directories like ab, ac, ed, df, ea, e2, etc which are consuming a lot of space like 8 GB to 15GB. The 50GB Storage is almost fully used. Our Monitoring tool is now creating alerts because the threshold is reached. Our questions are :
  • How we can delete this files and remove this directories ?
  • Why the JBoss Server does not delete by himself ?
  • How we can know what directory can be delete ?
• Would like to check if it is ok the clean up domain/servers/server1/data/content and how should we do it?
• When we update a war, we find that old content folder in jboss-eap-6.3/domain/servers/[servername]/data/content folder are not removed, is this right? Why EAP did not erase old content ?
