Description Wolfgang Rupprecht 2013-08-07 14:55:54 UTC 
Description of problem:
this happened when I enabled ipv6 pings in smokeping.

*** Probes ***

 +FPing6

 binary = /usr/sbin/fping6 

....

*** Targets ***

 probe = FPing6 

see: http://oss.oetiker.ch/smokeping/probe/FPing6.en.html

SELinux is preventing /usr/bin/perl from using the 'signal' accesses on a process.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that perl should be allowed signal access on processes labeled smokeping_t by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep perl /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
