Description Kevin L. Mitchell 2015-04-11 15:33:01 UTC
Description of problem:
SELinux is preventing syslog-ng from 'unlink' accesses on the lnk_file log.

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

If you believe that syslog-ng should be allowed unlink access on the log lnk_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 syslog-ng /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
