[Pacemaker] patch: pingd RA

[Dominik Klein]

High: RA pingd: Set default ping interval to 1 instead of 0 seconds.
Produced high load and traffic.

xen-03:~ # cat /proc/loadavg
1.53 1.54 1.47 4/213 6733
xen-03:~ # ps aux|grep pingd
root      6735  0.0  0.0   5284   808 pts/1    S+   09:52   0:00 grep pingd
root     17399 40.7  0.0  65316  1620 pts/1    S    08:59  21:35
/usr/lib64/heartbeat/pingd -D -p /var/run//pingd-pingd -a pingd -d 5s -h
10.2.50.11 -h 10.2.50.40 -h 10.2.50.8 -h 10.2.50.102

And that's in an otherwise idle cluster.

Until the next release, I'd strongly encourage anyone using the
pacemaker pingd RA to define an instance attribute "interval" with a
sane value or apply this patch. But of course, that's just me.

Regards
Dominik
