I am playing with 'small/beautiful stuff' like
bbox/uclibc.
I ran oom_trigger soon after boot and took
"top b n 1" snapshot after OOM kill.
Output puzzles me: total virtual space taken by *all*
processes is ~23mb yet swap usage is ~90mb.
How that can be? *What* is there? Surely it can't
be a filesystem cache because OOM condition reduces that
to nearly zero.

I think VIRT is a total virtual space taken by process, part of
which may be swapped. VIRT can't be reduced by swapping out -
correct me if I'm wrong.
But I believe even if I'm wrong on that, I simply do not have
90 mbytes to be swapped out here!
Look again at top output - most processes are below 1mb,
many are below 50k thanks to dietlibc.

It's a rather nifty utility from daemontools package.
It my case, it is built with dietlibs. Yes, it is
really takes only 20k of virtual memory when running!
# ldd supervise

# ls -l supervise

If you don't like it's license, then look here

I think I will lose "it's impossible" argument,
because all processes will be more than 1 mbyte in VIRT.
I will try nevertheless.

I always went by:
VIRT = RES + SWAPPED OUT
$ ps aufwwx | grep mingetty
#user pid %cpu %mem vsz rsz
root 2490 0.0 0.2 1548 552 tty1 Ss+ Oct25 0:00 /sbin/mingetty tty1
$ swapoff -a ## for fun
$ ps aufwwx | grep mingetty
root 2490 0.0 0.2 1548 632 tty1 Ss+ Oct25 0:00 /sbin/mingetty tty1
So to say, VIRT = RES + SHR + SWAPPED OUT, probably.

Have <= 128 MB RAM? Have a heavy busy system (even with >= 128)?

Ph... you're missing upx -9 on supervise ;)

Remember that glibc might be shared amongst processes, so *each* process will
have the 1 mb listed, though swap might stay at 0 if there is nothing else
which causes swapping.

128mb. System was idle, fresh after boot.
Seems I wasn't clear enough. I will try harder now:
Even if I add up size of every process, *counting libc shared pages
once per process* (which will overestimate memory usage), I arrive at
23mb *total memory required by all processes*. How come kernel
found 90mb to swap out? There is NOTHING to swap out except those
23mb!
(Of course when oom_trigger was running, kernel first swapped out
those 23mb and then started swapping out momery taken by oom_trigger
itself, but when oom_trigger was killed, its RAM *and* swapspace
should be deallocated. Thus I expected to see ~20 mb swap usage).

Let's get top(1) out of the equation. Could you grab VSZ from directly
from /proc/?

Just a thought: do you have a tmpfs mounted anywhere?

I did more testing. It does not happen right after boot.
It is not 100% reproducible, I *think* I need to fill pagecache
with filesystem cache first
(grep -rF qjklwmhflakwghfjklah $source_tree does this nicely)
and let the box sit idle for a minute or two.
Then I run oom_trigger. Typically it eats ~350mb and is killed.
That is, when things are working normally.
But sometimes it eats only ~250mb, and top before/after that looks
like this:
before oom:
top - 08:14:12 up 15 min, 1 user, load average: 0.37, 0.14, 0.06
Tasks: 78 total, 1 running, 77 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.4% us, 1.1% sy, 0.0% ni, 94.2% id, 4.2% wa, 0.1% hi, 0.0% si
Mem: 112376k total, 108564k used, 3812k free, 14968k buffers
Swap: 262136k total, 2592k used, 259544k free, 80516k cached
after oom:
top - 08:14:27 up 15 min, 1 user, load average: 0.52, 0.18, 0.07
Tasks: 78 total, 1 running, 77 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.4% us, 1.3% sy, 0.0% ni, 93.4% id, 4.8% wa, 0.1% hi, 0.0% si
Mem: 112376k total, 107704k used, 4672k free, 10336k buffers
Swap: 262136k total, 84168k used, 177968k free, 4056k cached
Both mem and swap 'used' values look strange.
Complete top outputs are attached.
Subsequently I automated the thing, and another such
event was captured (tarball of /proc/N/status before
and after OOM is attached):
#!/bin/sh
cd status_before
echo "PID.... Before......................... After......................"
for b in *; do
a=../status_after/$b
echo "$b:"$'\t'`grep VmSize $b`$'\t'`grep VmRSS $b`$'\t'`grep VmSize $a`$'\t'`grep VmRSS $a`
done
PID.... Before......................... After......................
