[SQU] Error in logs?

Hi all,
           while doing a general look at logs, I noticed on our squid box in
/var/log/messages:
Sep 7 08:13:36 roseanne squid[106]: idnsCheckQueue: ID 62: giving up after
20 tries and 48.9 seconds
   Jut wondering what caused this error and if its bad and can it be
fixed/stopped? Ive looked at the FAQ and couldnt find anything with 'idns'
in it...
All help is appreciated.
Regards,

Warren Smith.
