Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I noticed this while running a performance test with JMeter. For first half an hour everything was fine and the /server/all/tmp directory size was around 36M.

Then suddenly the tmp directory grew up to 6.1G. The space was taken by jar files inside vfs-nested.tmp. If I let the server sit idle there is no such behaviour.

I found https://jira.jboss.org/jira/browse/JBAS-7126 but adding that config made no difference.

Edit: Starting up with -Djboss.vfs.forceCopy=false does not create such directory at all. But does that affect clustered setup somehow?

Some discussion: https://community.jboss.org/thread/150212

Deployment using MainDeployer seems to be the cause as this problem did not happen when deploying exploded ear manually in to the server/all/deploy.
