Description Brian J. Murrell 2022-05-18 17:14:50 UTC
SELinux is preventing /usr/lib/frr/watchfrr from using the setpgid access on a process.

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

If you believe that watchfrr should be allowed setpgid access on processes labeled init_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:
# ausearch -c 'watchfrr' --raw | audit2allow -M my-watchfrr
# semodule -X 300 -i my-watchfrr.pp
