  greenpref            red                            started
Segmentation fault



Expected results:
No segfault

Additional info:
It also looks like rgmanager doesn't process other events if it processes a
network event.  For instance, status checks seem to be delayed.

Comment 1 Lon Hohberger 2005-03-02 12:08:49 EST

The segfault was a SM plugin problem.  We weren't zeroing out the
cm_addrs field when reading from /proc/cluster/services.

The processing-event part was just incorrect logic in main.c of rgmanager.
