We`re having problems too.  In addition to getty's dying, the init's
for the ports with modem control stop listening for DCD, which should
cause a getty to be started for that port.  I can fix that by killing those
init's with "kill -INT nnn".  The new init's seem to work for awhile before
they hang.  Any suggestions or bug fixes will be appreciated.  We`re running
4.2bsd on a Vax11/750 with 2 DEC DMF-32's.  Our other systems have dz's--no
problems.
