:SELinux is preventing /usr/lib64/xulrunner-2/plugin-container from 'getattr' accesses on the file /proc/sys/kernel/modprobe.
:*****  Plugin catchall (100. confidence) suggests  ***************************
:If you believe that plugin-container should be allowed getattr access on the modprobe file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:allow this access for now by executing:
:# grep pool /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

This this seem to block anything?  Any idea what plugin might have cuased it.
Comment 2 Vasil Draganov 2012-07-20 06:48:00 EDT
No, I didn't noticed any malfunctions.
I have no idea wich plugin is causes this. Here is some info about used plugins:
Mozilla Firefox 13.0.1 
Plugins - DivX Web Player v.; Gnome Shell Inegration; IcedTea-Web 1.2 Plugin; iTunes Application Detector; QuickTime Plugin-in 7.6.6; Shockwave Flash 11.2 r202; VLC Multimedia Plugin; Windows Media Player Plug-in 10.
I hope this helps.
