I'm just guessing here, but this is probably because apache is trying to
spawn new processes, and they keep dying because there's no memory.

There was discussion about this on PerlMonks:

The most informative quote was this one:
"$^M was an Ilya-thing, which he added in during his work on perl's
built-in memory allocation system. Nobody else ever really cared about
it so far as I remember from p5p, so it suffers some from both neglect
and unfinshedness. I remember in the 5.004/5.005 days that it used to
work, but I honestly don't remember how, nor whether it ever worked for
anyone other than Ilya."
