Description John 2011-05-03 10:29:42 UTC
SELinux is preventing /usr/bin/php-cgi from 'read' accesses on the file psched.

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

If you believe that php-cgi should be allowed read access on the psched 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 php-cgi /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

You will need to allow it using a local policy because that would allow all apache processes to read network config.

# grep php-cgi /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp


Do you know what 'psched' is?
