SELinux is preventing /usr/lib64/seamonkey/plugin-container from unix_write access on the semaphore Unknown.

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

If you believe that plugin-container should be allowed unix_write access on the Unknown sem 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 plugin-containe /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
