I apologize if this is the second posting. I sent the first one to the old
address.

System:        969/KS400
Operating System:   Version 5.0
Sessions: 310-320
Batch Jobs:    7

I am writing this while I wait on HPRC to call me back.  SOS and Glancexl
are showing P42 and P43 (owned by the system) making 50-60 I/Os per second.
 SOS tells me they are writes.  Both Pins are in the "A" queue at 13.  They
are averaging 3-4% of the CPU.  P11 is beginning to show 40-50 I/Os per
second.

An examination of the logfiles reveals nothing unusual.

:SHOWPROC 42;SYSTEM reveals
QPRI=A13; CPUTIME = 1:25:45; STATE=WAIT; PIN=42; PROGRAM=(..)

:SHOWPROC 43;SYSTEM reveals
QPRI=A13; CPUTIME = 1:24;44; STATE=WAIT; PIN=43; PROGRAM=(..)

We restarted the system on Tuesday at 1:30 PM.  Does this mean that approx..
8% of my CPU is spent caring for these two processes?  Does anyone know what
these 2 pins are doing?

I notice this same symptom when we first installed the box.  The number of
hits to the disc were high  with only 1 session and console.  The I/O
controller card was replaced because of system hangs during backup.  The
high disc I/Os went away.

Anybody with ideas?  I am still waiting on the Response Center.

HPRC does not believe this is a hardware problem.

thanks
roger
