:SELinux is preventing /usr/bin/python from using the 'signal' accesses on a process.
:*****  Plugin catchall (100. confidence) suggests  ***************************
:If you believe that python should be allowed signal access on processes labeled tuned_t 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 tuned /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp
