running kproc PID 514 on a RS6000/320/8Mb/120MB

Post by Fred Huc » Sun, 21 Jul 1991 22:10:50



Hello netters, we have two 6000/320, one with 16MB Mem. and two SCSI drives
and one with 8MB Mem. and one internal 120 MB Disk. On the 8MB machine there
is a kproc (PID 514) running with Priority > 0 that seems to eat a big part
of the CPU time. Here is a ps -kf :
     UID   PID  PPID   C    STIME    TTY  TIME CMD
    root     0     0 120   Jun 23      - 15:28 swapper
Quote:>   root   514     0 114   Jan 01      - 27674:53 kproc <

    root   771     0   0   Jan 01      -  5:08 kproc
    root  1028     0   0   Jan 01      - 38:22 kproc
    root  1285     0   0   Jan 01      -  0:00 kproc
    root  1632     1   0   Jun 23      -  0:00 kproc
    root  2629     1   0   Jun 23      -  0:00 kproc
The kproc 514 is running all the time. On the other 320 the same kproc has
Prio. = 0 just like all the others.
Can someone tell me if this is normal ? Thanks in advance,

Yes. It seem to be normal.

If you what to see which process takes most of cpu time, take
monitor-1.04.2.tar.Z from nic.funet.fi (128.214.6.110). It's in
directory /pub/unix/AIX/RS6000.

The monitor program mentioned in another article in this thread shows
that this kproc is the "wait" process, which 'eats' all the idle CPU
time.  This is perfectly normal behavior.

Interesting that "swapper" and "wait" have radically different STIMEs....
hmmm, my machine's "wait" STIME is Dec 31... it might be interesting to
go sniffing about in "wait"'s date structure.  An exercise for the curious.

The 514 process is the "wait" kernel process.
This means your machine spend 10% of its time "wait"ing (slow disk?)

1. RS6000/320: SCSI Pinout/external SCSI disk

We have an IBM RS6000/320 and want to try third party external disk
on it.  Does anyone have the pinout of that odd 60pin connector IBM
uses for SCSI?

On a similar subject, anyone else out there had success putting third
party disk on a RS6000 and making it work?
