Nsd process defunct during reload after notify

Hi,

I am testing nsd-3.2.1 on Centos 5.2 x86_64 and noticing nsd process becoming defunct/zombie every time it reloads after a notify. the logs doesn't indicate anything out of ordinary.

from top:
  4325 nsd 25 0 0 0 0 Z 11 0.0 0:04.98 nsd <defunct>

Anyone else testing 3.2.1 and having similar issues ?

Regards,

Vicky Shrestha
