/opt/quest/bin/vastool join hangs on applying group policy settings you see the following last line:
A stale lock file has a hung vgptool process. This should not happen unless it was run in the foreground or by a process other than vasd. Every vgptool process spawned by vgptool has a signal timeout that will fire and destroy the process which cleans up the lock file. We recommend not using vgptool in a scheduler.
