- Could anyone confirm problems using the on-board
- comm port on a VAXStation 2000 under Ultrix 4.2A ???
-
- I suspect an interrupt latency or priority problem
- w/ this device in the Ultrix 4.2 implementation. Awhile
- back I was testing a SLIP server by attaching a Mac to
- the back-end of the VAX and logging into it to start
- sessions. After a few minutes of exerting SLIP traffic
- over the hardwired connection - the kernel would panic
- and crash dump. The only error log messages I could find was
- a SILO overflow warning.
-
- SInce that point - the machine has been in service
- providing dial-up SLIP service over LAT connections to our
- Xyplex. There have been no panics , crash-dumps or
- slowdowns even when I saturate multiple connections with
- traffic.
-
- Just want to confirm the suspicion if anyone
- else has observed the same problem.
