STABLE-20040123 + OVDB: nnrpd dies on signal 11

[Matti Saarinen]

I've just installed a new news server and today I put it in the
production use. Now, it seem there are problems with the interaction
of nnrpd processes and ovdb_server. The system has now been up 7 hours
and 11 nnrpd process have exited on signal 11. A few but not all have
dumped core as well. 

The nnrpd dying on signal 11 seems to be connected with these lines
appearing news.notice:

  nnrpd[18027]: OVDB: rc: cant write: Broken pipe

At the moment, the are 56 nnrpd procesess that have logged the message
above. Ten of them have died on signal 11  and three of those have
dumped core.

If I check the core dump with gdb the backtrace looks like this:

[the similar lines seem to continue forever]

The system runs FreeBSD 4.9-STABLE. It has been compiled from cvsuped
sources on 2004-02-06.
