Description Lon Hohberger 2011-10-18 19:29:09 UTC 
Description of problem:

If you kill rgmanager at just the right time during event processing during startup, it can throw errors in to the logs:

Oct 18 15:26:30 snap rgmanager[15382]: Shutting down
Oct 18 15:26:30 snap rgmanager[15382]: Stopping service service:b
Oct 18 15:26:30 snap rgmanager[15382]: Service service:b is stopped
Oct 18 15:26:30 snap rgmanager[15382]: #45: Unable to obtain cluster lock: Bad file descriptor
Oct 18 15:26:30 snap rgmanager[15382]: #50: Unable to obtain cluster lock: Bad file descriptor
Oct 18 15:26:30 snap rgmanager[15382]: #13: Service service:wtf failed to stop cleanly
Oct 18 15:26:30 snap rgmanager[15382]: #55: Unable to obtain cluster lock: Bad file descriptor

Version-Release number of selected component (if applicable): 3.0.12.1-4.el6

How reproducible: 10%

Steps to Reproduce:
1.  service rgmanager start
2.  sleep 8
3.  service rgmanager stop
  
Actual results: Errors in logs.  This occurs because we close the lockspace while other threads are trying to acquire locks.

Expected results: No errors, clean shutdown.

Additional info: This does not look like a high-risk condition, but it is a lot of noise.
