DNS reboot causes purples

Hi all,

I'm hoping someone might be able to help me.  I'm running Hobbit 4.1.2 on a
Fedora Core 4, monitoring approximately 500 servers.  I have been running
Hobbit for a few months and a few times our DNS server has been rebooted for
patching.  When this happens it causes some servers to go purple and the
only way I've been able to fix this is to restart the Hobbit service but it
has generated a ton of alerts and not a lot of happy alert recipients.  My
/etc/resolv.conf file has primary and secondary DNS servers, so I would have
thought if one wasn't available it would use the other, but this doesn't
seem to be the case.
Has anyone seen this or know what I could do to prevent these purples from
occuring when the DNS server is rebooted?

Thanks much in advance.
