I'm running NetBSD-1.3F (July 22 sources or so) on an 386/33, 8MB RAM.
The machine's been up and working fine for 39 days, but last night, su
and syslogd quit working. If I su and enter root's password, su hangs in
ttyout:

  UID   PID  PPID CPU PRI NI   VSZ  RSS WCHAN  STAT TT       TIME COMMAND
    0 16483 15023  13   4 -2   156  556 ttyout T<   p3    0:00.36 _tcsh (su)

If I enter the wrong password, su says "Sorry" before it hangs:
  UID   PID  PPID CPU PRI NI   VSZ  RSS WCHAN  STAT TT       TIME COMMAND
    0 16485 15023  12   4 -2   156  560 ttyout T<   p3    0:00.33 su

syslogd's not logging anything either, and it's also stuck in ttyout:
  UID   PID  PPID CPU PRI NI   VSZ  RSS WCHAN  STAT TT       TIME COMMAND
    0   127     1   0   4  0    80   12 ttyout IWs  ??    4:18.30 syslogd

Any ideas? The kernel doesn't have ktrace or ddb, so I probably can't
get too much more info. I need to su too, so I'm gonna reboot, although
I can make it save a core dump first...
