I'm not sure about the segfaults, but we are facing the same issues on
RHEL5 and FC6, i368 - random failovers due to ip-check failures. This
workaround seems to help, for now at least:

I'll check if it is indeed the ping segfaulting and report back when I
get some time.

We reinstalled our machines with RHEL 5 x86_64 (we were running i386) a
few weeks ago and the mysterious IP monitoring failures have
disappeared. I believe it was postulated that a compiler bug regarding
-fpie might be causing segfaults in i386 binaries, so this would support
that theory to some degree, although I did not really attempt to confirm
it further. I thought the architecture change fixing the random
failovers was noteworthy.
### previous thread below
Hi Chris,
I am experiencing the same problem on RHEL 5 and I have a support
request in with RedHat.
I was asked to increase the debug level by changing the <rm> line in the
cluster configuration to:
<rm log_facility="local4" log_level="7">
I then needed to add "local4.* /var/log/cluster" to /etc/syslog.conf and
run "service syslog restart".
To update the cluster configuration I needed to propagate the cluster
configuration to both nodes:
# ccs_tool update /etc/cluster/cluster.conf
After a week I have not had the problem with the increased logging
despite the problem occurring regularly prior to that - 2 to 3 times a
day. One day last week out of curiosity I reverted to the default
settings and within a few hours I had the failure to ping error on one
of the clustered IP addresses and the service was restarted.
I now have the logging back at 7 and the support request is pending.
Regards
