Net::OpenSSH memory allocation error with seemingly low memory code

DanBev has asked for the wisdom of the Perl Monks concerning the following question:

Hello Monks, I appeal to your wisdom for an advice.

I have an "unable to fork ssh master: can not allocate memory" error when using Net :: OpenSSH-> new.
I know that this kind of error is spy for unoptimized code, but unfortunately I have a code of 9000 lines that I can't for obvious reasons post (and I know that's very blamable). I am also aware that with a code so long the chance to have bug in the code is virtually 1.

The only thing I ask is: is it possible to have a "can not allocate memory" if checking the program execution with "top" I see that the memory allocation is practically negligible? How can it be?

Thank you all.

`fork` is failing for some reason. You must investigate why! Try running your program under `strace` in order to see what is happening at the OS level.	[reply] [d/l] [select]
