[Pacemaker] pingd process dies for no reason

[Patrik.Rapposch at knapp.com]

we already made changes to the interval and timeout (<op 
id="pingd-op-monitor-30s" interval="30s" name="monitor" timeout="10s"/>).

how big should dampen be set?

please correct me, if i am wrong, as i calculate it as following:
assuming the last check was ok and in the next second, the failures takes 
place:
then we there would be 29s till the next check will start, and another 10 
seconds timeout, plus 5 seconds dampen. this would be 44 seconds, isn't 
that enough?

thx,

kr patrik

5s is way too short.
