Description Renich Bon Ciric 2013-10-16 16:56:18 EDT
Description of problem:
I restarted nginx. I suppose a thin-enabled website caused this. Thin is a ruby application server.
SELinux is preventing /usr/bin/ruby-mri from 'block_suspend' accesses on the capability2 .

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

If you believe that ruby-mri should be allowed block_suspend access on the  capability2 by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep ruby-mri /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
