bind: eating a lot CPU time

Wed Dec 5 09:31:07 UTC 2012

On a CURRENT server acting as the gateway/router (FreeBSD 10.0-CURRENT
#1 r243869M: Wed Dec  5 00:09:59 CET 2012), a running named/bind service
for local DNS resolution is eating up a lot of time.

Is this usual? I can not see caching, checking for requests or similar
what could cause a permanent load on the server daemon.

regards
