That's what the "-b" is for -- it does its thing then quits. Try it.

When that happens, you can do something like
grep -h ^Vm /proc/[0-9]*/status | grep -v VmLck | sort | uniq -c | sort
and look for big numbers, or lots of smaller numbers. Once you find them,
grep '<parameter>: *<number> kB' /proc/[0-9]*/status
^^^^^^^ tab, space
will give you the PID, and
ps <PID>
will give you the name.
I'm sure there's a less convoluted way to find out, but that's the first
thing that came to mind.

Maybe a bunch of smaller processes? Especially statically-linked ones.
Pre-launched httpds?
