After we installed Ultrix3.1 on our VAX 8530 plus several patches concerning LAT terminal connections and DECNET, we got at least one crash per day: panic: m_free has bad m_cltype The sequence of calls according to the dump is _Xnetintr(...) ... _latintr() ... _process_vc_run(...) ... _m_freem(...)... _panic(...)... I have the suspicion that the problem is related to dial-in modems for uucp traffic being connected via a portselector (GANDALF) to DEC Terminal servers for connection to the 8530. When I disabled uucp login for about a day, crashing stopped. We have reverted to the 3.0 kernel for the time being and have not seen these crashes any more, however, we are now again suffering from the tape problems of Release 3.0. A tape with several dumps has been sent to our local DEC support, but we have not got any fix so far. Has anybody had a similar experience? Any ideas? Your help will be much appreciated.
