DNS lookup timeout ERROR

[sh4ka]

One of my customers uses Webmasters Tools from google , looking at what pages he have indexed by Googlebot, found that 180 pages are giving a "DNS lookup timeout" error, tried searching for help on google and the only thing that i found is " We received a timeout on DNS lookup."

DNS are ok, same as the zone file, everything is responding OK, I dont know what can be the issue.. ? any ideas ?

Im using cPanel + RHES 4.

Thanks.

If it is in the last 24 hours, there might not actually be any problem ...
