Subject: pre6 oddity

Hi Marcelo,

On two of my machines running pre6, I am seeing top report very odd
priorities for two kernel tasks:

  PID USER     PRI  NI  SIZE  RSS SHARE STAT %CPU %MEM   TIME CPU
COMMAND

    8 root     18446744073709551615 -20     0    0     0 SW<   0.0
0.0   0:00   0 mdrecoveryd
   16 root     18446744073709551615 -20     0    0     0 SW<   0.0
0.0   0:00   0 raid1d


Something related to the scheduling changes going on ?

(RedHat 9 base system)

Hi Marcelo,

This was a procps bug. 2.0.11 I believe. There was something like a
printf("%ull", prio) with prio=-1, which prints 2^64-1 (the high number seen
here). Upgrading to 2.0.13 fixed the problem for me.

Cheers,
Willy

Confirmed - I updated to procps 3.1.11 and the oddity with the display
is gone.

Thanks Willy.
