Description of problem:
- Fedora 30, with updates as of yesterday (I think).  Including new selinux policy update
- running spamassassin
- recent selinux policy from Fedora updates fixed an issue that prevented /usr/share/spamassassin/sa-update.cron running [Bug 1705331] 
- I think that this then exposed the current issue.
SELinux is preventing pgrep from 'getattr' accesses on the directory /proc/<pid>.

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

If you believe that pgrep should be allowed getattr access on the <pid> directory 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 'pgrep' --raw | audit2allow -M my-pgrep
# semodule -X 300 -i my-pgrep.pp
