I've just started administering a Sun 4/280 file server, and I'm
experiencing what people have said to be a persistent problem.  The unit
is a rack-mount system with what I believe is an ALM board (I haven't
figured out the Sun codes yet) with 16 serial ports hooked to it (numbered
0-15, which corresponds to tty00-tty0e).  Every so often, at no
predictible interval, the board will hang and the terminals attached will
be useless.  Killing the getty and re-starting it has no effect; I have to
reboot the machine to get things fixed.  Any ideas?  We're running SunOS
4.0.3.  Thanks for any help.
