[Pacemaker] Strange error message with the ocf:pacemaker:ping resource

[Fabian Portmann]

Hi

we do have the same issue:
The ping resource works but when I enter
crm_mon -A1
I get    
+ pingd                             : 0         
crm_glib_handler: Cannot
wait on forked child 28294: No child processes (10)
+ pingd                             : 0         
crm_glib_handler: Cannot
wait on forked child 19196: No child processes (10)
+ pingd                             : 0             
: Connectivity is lost

There should be only the last line which states 
+ pingd : 0 or + pingd : 11000 
on a working cluster. The cluster's degraded at the moment.

Our environment:
CentOS release 6.5 (Final)

Any ideas?
