Description Frank Murphy 2011-06-17 12:06:46 UTC
SELinux is preventing /usr/sbin/lldpad from 'create' accesses on the shared memory Unknown.

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

If you believe that lldpad should be allowed create access on the Unknown shm 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 lldpad /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
