Strange DNS problem

Hi,

I am a bit confused on a sort of DNS problem.

My server stops responding after 10 days and i need t manually kill the named process and restart it to get it going as before. The server load is almost nil.

The named suddenly start taking 95% of CPU usage and a very high RAM usage and everything is in standstill. Otherwise my server behaves very nicely and without any problem.

Is this any attack ?

Any suggestion are welcome.

Regards
Abhishek Rungta
