I have upgraded my cube to NeXT OS 2.0 with the 68040, added memory and
some peripherals- and have been getting some spooky intermittent problems.
I was wondering if anyone else has experienced these problems and could
suggest solutions.

FIRST, I added a PLI drive in a SCSI chain that goes from an external HD,
to the PLI drive, and then to a scanner.  I seem to lose the PLI drive 
periodically with zillions of repeated messages like:

  Mar 30 10:15:47 ljkiraly mach: sd2 (4,0): ERROR op:0x0 sd_state:2 scsi status:0x0
  Mar 30 10:15:48 ljkiraly mach: sd2 (4,0): ERROR op:0x0 sd_state:2 scsi status:0x0
  Mar 30 10:16:17 ljkiraly last message repeated 24 times

These continue until I power cycle the PLI drive.  I added an external SCSI line
terminator to the scanner (which is supposed to be internally terminated)- which
has seemed to help but not solve the problem.  Any suggestions?

SECOND, I get a lot of console messages like:

Mar 29 10:39:33 ljkiraly Workspace[1195]: cheap: dropping extra collection sequence=5
Mar 29 10:43:20 ljkiraly Workspace[1195]: cheap: dropping extra collection sequence=7
Mar 29 10:45:11 ljkiraly Workspace[1195]: cheap: dropping extra collection sequence=10
Mar 29 10:50:18 ljkiraly Workspace[1195]: cheap: dropping extra collection sequence=12
Mar 29 10:52:37 ljkiraly Workspace[1195]: cheap: dropping extra collection sequence=15
Mar 29 10:53:56 ljkiraly Workspace[1195]: cheap: dropping extra collection sequence=17

Theses messages don't seem to effect anything directly- but I worry about them
because THIRD, I periodically core dump when logging out.  I have also 
experienced a number of problems when logging in as root and having problems
launching standard apps like Terminal- these apps go into a launching status 
and never complete.  I have to kill them from a processes window- and I cannot 
launch them again until I logout and login again.   Finally, on a few occasions
I have gotten alert panels on logging in that describe an "internal error-  
continue at your own risk" kind of message- to which I respond be either 
rebooting or power cycling the machine.

Is anyone else experiencing these problems?  Any recommendations?
I really lover my NeXT- but find these problems a little aggravating, since
I never experienced them with my slow '30 version 1.0 system.
