vmunix: BAD TRAP; vmunix: getty: Text fault

[Rich Winkel-UMC Math Department]

SunOS 4.0.3 on a Sun 4/110: If an ALM-2 dialup port hasn't been used in
awhile, the first attempt to connect to it results in the Sun dropping DTR
and hanging up immediately after displaying the login prompt.  If I call
back immediately after this, it behaves normally.

Occasionally, the first connection attempt results in a system crash and
the above messages.  If I kill the getty's in question periodically and
let init re-fork them, everything works fine.  Has anyone else seen this
behavior?

Thanks,
