Hello,

I suspect the problem is in:
--rwxrwxr-x M 21231 glenda sys 311768 Jul 14 11:46 dns

I don't have 2012/0501 version. I am lazy sorry.

My current dns is
--rwxrwxr-x M 131526 sys sys 310819 Apr 13 12:46 /386/bin/ndb/dns
That works 12 days since last boot without any troubles.

ar% ps
....
none             99    0:00   0:00      184K Open     listen
none            100    0:00   0:00      184K Open     listen
bootes          540    0:00   0:01      240K Await    patrol

arisawa      241202    0:00   0:00      360K Pread    pop3

where patrol is a program that reboot cpu server if it detects a process =
that stops
with Fauth status. the contents is=20
ar% cat /usr/bootes/bin/rc/patrol
#!/bin/rc
rfork e
while(sleep 60){
  a=3D`{ps|grep Fauth|wc}
  if(! ~ $a(1) 0){
    /usr/local/bin/386/logit -l reboot Fauth:$a(1) # for logging (my =
program). don't mind
    reboot
  }
}
ar%=20
