Help on panic: "closef: starting count < 1" on 4.2bsd (Vax 750)

[David Melman]

panic closef: starting count < 1

This is happening a couple times a week on our vax 750 running 4.2bsd.
We have UDA-50 disk controller (ra60,ra81) and a dmz.

This last time I noticed it coincided with killing of a 'lock' process
that was going wild.  The process was associated with the dmz tty port.

Please E-mail directly any suggestions,

Thanks for you help!
