It seems some changes in were introduced in Fedora 13 that broke nagios.
audit2allow suggests

#============= ping_t ==============
allow ping_t nagios_log_t:file { read write };
but I think some transition is missing for ping_t -> nagios_t here
</pre>

<pre wrap="">
Actually its the other way around.
There is a domain transition for nagios_t to ping_t which probably should be removed:
netutils_domtrans_ping(nagios_t)
.. and be replaced by:
netutils_exec(nagios_t)
Could you please report a bug for this?
</pre>

Actually this is a leaked descriptor. There is a domain transition for
check_ping plugin that runs in nagios_services_plugin_t domain<br>
<br>
netutils_domtrans_ping(nagios_services_plugin_t)<br>
<br>
and I want to keep it. But we can remove <br>
<br>
netutils_domtrans_ping(nagios_t)<br>
<br>
and we will dontaudit<br>
