I have been seeing an interesting problem on a Sun 4/280 I have
been using to do some dr11-w development. When the interface is
very busy (sending continuously for long periods, minutes), console
messages will occasionally stray off to /dev/ttya instead of going
to the console. Has anyone else seen this before? Is it perhaps
a peculiar side effect of the DELAY(x) kernel macro? Broken hardware?
Configuration: Sun 4/280, xylogics disk controller, standard scsi tape,
fujitsu 9 track, Super-Eagle, 32Mbytes of memory, and an IKON 10089 DR11-W
interface board in a VME2-3 adapter in the last slot.
As long as I'm asking, any thoughts on why selection_svc won't die like
a good little process should when I exit suntools (or root, guest, etc. for
that matter)?

If so, I "presume" I can expect the problem anytime the system gets particularly busy. Atleast its better than not getting the messages anywhere at all (although they still end up in /usr/adm/messages). /* Jim Hutchison UUCP: {dcdwest,ucbvax}!cs!net1!hutch ARPA: JHutchison@ucsd.edu These are my opinions, and now you have your perceptions of them. */
