[nos-bbs] bad header >> wigged out interface

I've been having this problem for a while. It happens every few days.
Maybe someone else has seen it and can tell me what's going on and, more
importantly, how to fix it.
See the partial interface trace log below. At line 18, we see "bad
header!".
The next thing we see, starting at line 22, appears like the interface lost
its mind. This one log entry continues until line 729.
Following that, is another similar log entry of about 720 lines filled with
garbage.
At that point the port is hosed. By that, I mean inbound connects are
ignored and I start getting "DM received" messages when I try to connect
outbound. Also "tail -f" of the log does not match what's actually
happening on the air. It's like it's several minutes out of sync. (trace
log sync is set to 1 second.)
The TNC is a Kantronics KPC-3+ and I've replaced it with a new one. Same
problem. It is set to hardware flow control. I run 6 machines, each with
multiple ports using the same type of TNC, and this only occurs on this one
port. The only recovery I know of is to reboot JNOS.
As I see it, there are two problems:
1) JNOS is losing its mind and gets into an unrecoverable state.
2) If there is some external cause, JNOS is not telling me what it is that
it doesn't like.
Any suggestions?
