Subject: Re: John does not fork as many times as I want

I've omitted to tell something:

after these missing forks, the main process returns me:

1:Fork: cannot allocate memory

which explains why all forks are not poped. However it seems that I
still have plenty of available memory (about 200GB free).

Can this error come from another situation than lack of memory?
