Warning from admin for running script Can't Post

I am newbie
Can somebody explain me why I got this warning from admin for running a Perl script
=========
Hi Rxxxxxxx,
please check your perl scripting, you are forking without obvious control in
your pin.pl script.
This is not intended usage of a loginserver.
The host was endangered due to swapping, so I had to kill your script.
Please take more care of what you are doing on a loginserver.

Regards,
Lxxxxx

Re: [lork] Warning from admin for running script [In reply to] Can't Post

They are telling you that your script is creating too many processes and doing a lot of disk I/O.

Is your script calling itself vis a system call in a loop?

Can you post your script?
