Description mdeggers 2011-04-30 18:27:40 UTC
SELinux is preventing /usr/sbin/vnstatd from 'getattr' accesses on the file /proc/<pid>/net/dev.

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

If you believe that vnstatd should be allowed getattr access on the dev 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 vnstatd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
