Can someone help with this?
A dedicated server goes down around twice a day, all sites become unavailable, plesk, etc.
System is Fedora with Plesk installed.
At the same time interval I get in /var/logs/messages these errors:

lame server resolving and unexpected RCODE (SERVFAIL)
and
"lame server resolving"

This particular part seems to contains "(REFUSED)", others have "(SERVFAIL)", and this appears in same time when server becomes unavailable.
This is the only named/bind related log I could find, I suspect that the named service goes offline but I am not sure, can that be the cause of the above errors?
