Description Miroslav Grepl 2011-07-21 07:02:09 UTC 
+++ This bug was initially created as a clone of Bug #703010 +++

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 psad_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 psad /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
