DNS locked (no nslookup anyway)

[Boulton, Michael (Corp-Warren)]

  Greetings,

  I am still having problems with both of our DNS servers (inside and
outside) locking up once in
a while, not responding to nslookup.  Here is what is in the log:

Apr 11 10:46:06 coreadns1 named[435]: Cleaned cache of 0 RRsets
Apr 11 10:46:15 coreadns1 PAM_pwdb[1115]: (su) session closed for user root
Apr 11 10:46:17 coreadns1 PAM_pwdb[1092]: (login) session closed for user

Apr 12 08:10:00 coreadns1 PAM_pwdb[1576]: (login) session opened for user
mboulton by (uid=0)

  Anyone have any ideas? A reboot will fix it, but I would like it
permanently fixed.
