Description Lon Hohberger 2005-11-10 21:34:46 UTC 
Description of problem:

If signals occur quickly in sequence, it's possible for clulockd to deadlock
during a reconfiguration.


Version-Release number of selected component (if applicable):


How reproducible: 100%



Steps to Reproduce:
1.  service clumanager start
2.  while [ 0 ]; do killall -HUP clulockd; done

  
Actual results:

clulockd hangs, and causes timeout errors for connecting 


Expected results:

Normal operation.


Additional info:

Under high load conditions, an occasional timeout warning may occur; this is not
a cause for alarm.

A new *TEST* package build with several bugfixes (fixes bugzillas: 171637 172735
172893 172894 ) is available.  Gulm-bridge support has been disabled in this
release to prevent having to install with the "--nodeps" option:
