SELinux is preventing /usr/bin/tpprint from 'read' accesses on the fifo_file fd.

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

If you believe that tpprint should be allowed read access on the fd fifo_file 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 tpprint /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
