Description of problem:
SELinux is preventing abrt-hook-ccpp from using the 'sigchld' accesses on a process.

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

If you believe that abrt-hook-ccpp should be allowed sigchld access on processes labeled kernel_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 abrt-hook-ccpp /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
