VmRSS bug on 2.4.10?

[Edmund Lau]

Hi All,

I was doing a "ps aux" on my K6-3 machine running 2.4.10.  I haven't seen
this posted on the newsflash page yet so I'll post it here.  I noticed
that my X server was reporting something funny:

root       328  0.0  0.0  1004    4 tty4     S    Sep23   0:00 /sbin/getty
38400 tty4
root       330  0.2 99.9 24376 4294967072 ?  S    Sep23   3:56
/usr/local/pkg/X11R6-4.1.0/bin/X -auth /usr/local/pkg/X11R6-4.1.0/lib/X11/xdm/authdir/authfiles/A:0-fTtaTO
nobody   25244  0.0  2.4  5884 3064 ?        S    06:51   0:14
/usr/local/pkg/apache-1.3.20/bin/httpd

What in the world? 99.9% MEM?  At first I thought it was because I haven't
updated my ps tools and such, but they've been working just fine w/ all
the other 2.4.x kernels I've been running.

Next thing: cat /proc/330/status shows:

VmSize:    24376 kB
VmLck:         0 kB
VmRSS:  4294967072 kB
VmData:     5192 kB
VmStk:        68 kB
VmExe:      1328 kB
VmLib:      1092 kB

Wow!  Wish I had that much memory!  I thought I only put in a single
128meg PC-100 DIMM...  I don't think it's impacting normal functions, but
I'm not on the console to check if X (X11R6-4.1.0) is still working.

Anything I can do to help you guys figure it out?  It's a production
machine so I probably can't help with full blown debugging, but I'll
produce reports as long as someone tells me what to type in :) I'll leave
the X server alone for a week or so.  Please CC me as I'm not on the list.
