[comp.sys.next] write

I run an LPMud (a network game) on a NeXT running Mach 2.0, and I seem
to have a few problems that I didn't have with Mach 1.0.  The main
problem is, there is a write() statement in the C source code that
occasionally fails (randomly) and causes the program to exit.  What
could cause this?  It seems to happen most often when there is a large
network load (30 to 40 users playing at a time), but I have trapped it
even with a smaller network load.  The line reads

      if ((n = write (ip->socket, buff2 + offset, chunk)) == -1) { ...
}

where the ... checks errno.  This problem never seemed to happen with
Mach 1.0, or on other machines. (I have run on Vax, IBM)  One thing
only I changed when compiling in 2.0, and that is I had to add the
"-bsd" option, otherwise it seemed to have some problem with
inet_ntoa().  The -bsd made it compile (and seem to run) fine.

Does anyone know what could cause this write() to force the program to
exit, and does this -bsd option have anything to do with it?  I'd be
very appreciative of any help/advice.
