We have a Vax 11/750 running 4.3 BSD.  Since there is only one machine
running 4.3 BSD and we are not connected to the Internet, we decided 
not to run the nameserver (/etc/named).  We don't have a /etc/named.boot,
so that /etc/named will just exit upon startup.  When applications
tries to consult the nameserver, they will fail and fall back to /etc/hosts.
Sounds good?  So far so good.  

Recently, the MTBF has gone down to about 7 days.  After about 6 to 7 days,
some applications seem to go berzerk.  Under normal circumstances, the
code in gethostbyname() should fail in recvfrom().  But after about 
6 to 7 days, it starts failing in select() reporting a "timeout" instead.
(Note: I got all these by compiling gethostbyname(), res_send(), etc. with
DEBUG flag.)  The network is still working.  People who have rlogin'ed 
can still work.  New users cannot rlogin.  The vax is still forwarding 
packets between networks.  (Yes, our vax acts as an IP-router.)  But it
does not answer to ping anymore.

Has anyone seen a similar problem?  Please reply via e-mail 
to uunet!daisy!pkl since I'm not a regular comp.bugs.4bsd reader.  

And we thank you for your support ...
