I'm having problems with a NeXT server machine panic'ing the kernel
(Read: Crash & Burn).

The server is crashing with messages 'zone "objects" empty' 'receiver
buffer overrun' and 'panic: (CPU 0) zalloc' when the panic occurs.

Have any of you ever heard of anything like this?  I mean obviously some
zone is becoming fully allocated and something wants to allocate more --
but what, from where???   My problem is that right now I have no idea
where the panic is coming from.  (Possibilities include everything from
some strange flakyness with NFS to perhaps a problem with the modem
being set right for dialing in...)


On a related note -- would anyone know what can mess up /etc/utmp??? 
When I dialed in (this server is 300 miles away -- joy ;-(  ) about an
hour before the latest panic, I noticed that finger was returning warped
information about who was logged in, and for how long they had been
logged in....


Any ideas???



            Thanks,
