From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.1b) Gecko/20020722

Description of problem:
just upgraded to the newest beta release (from redhat 7.3), and 'ps' shows very
abnormal memory usage, neither 'cat /proc/meminfo', 'top' or 'free' shows
abnormal usage so I doubt it's a kernel-issue

Version-Release number of selected component (if applicable):
procps-2.0.7-21

How reproducible:
Always

Steps to Reproduce:
type 'ps aux'

Actual Results:  see URL

Additional info:

kernel 2.4.18-7.80
Comment 1 Peter van Egdom 2002-07-31 21:18:30 UTC 
I'm seeing this too (on a freshly installed Red Hat Linux Limbo (beta 2) 7.3.93).


This is the output I'm seeing on Red Hat Linux release 7.3 (Valhalla) :

USER       PID %CPU %MEM   VSZ  RSS TTY      STAT START   TIME COMMAND
root         1  0.0  1.5  1304  472 ?        S    18:10   0:04 init
root         2  0.0  0.0     0    0 ?        SW   18:10   0:00 [keventd]


and this is the output I'm seeing on Red Hat Linux release 7.3.93 (Limbo) :

USER       PID %CPU %MEM   VSZ  RSS TTY      STAT START   TIME COMMAND
root         1  0.0 4112.5 1256 5144576 ?    S    21:21   0:04 init [
root         2  0.0  0.0     0    0 ?        SW   21:21   0:00 [keventd]
Comment 2 Christian Karlsen 2002-08-01 00:01:51 UTC 
hmm, after some further researching I noticed it's a kernel issue, I tried with
2.4.19-pre10 and ps shows normal memory usage.
Comment 3 Jeremy Katz 2002-08-01 07:57:20 UTC 
cc'ing Arjan so he can confirm/deny it being a kernel issue
Comment 4 Arjan van de Ven 2002-08-01 09:11:58 UTC 
it all looks ok to me here..... but I'm using 7.3 top/ps on my laptop (but
limbo2 kernel)
Comment 5 Christian Karlsen 2002-08-01 14:38:41 UTC 
I copied 'ps' from my 7.3 box (procps-2.0.7-12), but it still shows weird memory
usage
Comment 6 Dax Kelson 2002-08-04 20:32:37 UTC 
limbo2:

The ps command is horribly miscalculating memory usuage, my box right now
has 256MB ram.

ps aux:

USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
rpc 492 0.0 2245.9 1400 5734400 ?  S 17:38 0:00 portmap
rpcuser 511 0.0 2316.5 1444 5914624 ?  S 17:38 0:00 rpc.statd
root    568  0.0 2213.8 1380 5652480 ?    S    17:38   0:00 /sbin/cardmgr

How can portmap be using 2000% of my memory?
Comment 7 Alexander Larsson 2002-08-07 11:22:19 UTC 
Sounds like it is a kernel issue, I'll take a deeper look.
Comment 8 Alexander Larsson 2002-08-07 16:09:35 UTC 
Yes. The rss field in /proc/pid/stat seems to be way off. Assigning to kernel.

Changing this to blocker, since the dup was a blocker.
Comment 11 Arjan van de Ven 2002-08-13 09:34:02 UTC 
Finally got a handle on this one and found a fix, will be in next build
Comment 12 Jay Turner 2002-08-16 04:36:40 UTC 
Looks pretty good with kernel-2.4.18-11.
