Hi David,

As you have already found, the problem is caused by the bug below:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=246623

in short: ping segmentation faults, which then returns a generic error. 
This causes cluster suite to wrongly think that the IP is unreachable so 
relocates/restarts the service. There's nothing wrong with the IP 
address, the network, or cluster suite.

You could possible modify /usr/share/cluster/ip.sh so that you 
workaround the problem (ie, check for return code 139 and if you get it 
try the ping again), or recompile the iputils package without the -pie 
flag - both are ugly hacks thou.
