Use of symbolic links leads to large disk usage in JBoss EAP

Issue

• The server configuration directories ($JBOSS_HOME/server/$PROFILE) are linked via symbolic links (symlinks) to another file system. That is, $PROFILE is a symlink.
• An application ear is deployed directly to the $JBOSS_HOME/server/$PROFILE/deploy directory without using symbolic links.
• When a new web browser session is started for the application, the $JBOSS_HOME/server/$PROFILE/tmp/vfs-nested.tmp folder doubles in size causing the file system to fill up very quickly when there are many concurrent user sessions.
• When we remove the symbolic links, everything works as expected and the $JBOSS_HOME/server/$PROFILE/tmp/vfs-nested.tmp folder does not double in size when a new session is created.
• Having problems with the ./tmp path, the subpath vfs-nested.tmp is consuming lots of space. The only fix we're aplying is restart the jboss.
• Vfs-nested.tmp is growing without limits.
