It is using all CPU time on the box. It seems to be answering queries alright, just using a lot of CPU.

[bug] libbind: isc's override of broken gettimeofday() implementions was not always effective. [RT #15709] It could be that I just need to scrap that machine... -- Scott Lambert KC5MLE Unix SysAdmin lambert@lambertfam.org
