Hi all:

   I am running a script to simulate login to webserver using a software 
call webcopy (written in Perl).

   The script will call the webcopy and put it to background. And this 
will continue for 1000 users. I found out that, it will stop at around 
280 users. Then the error message, cannot fork will appear. 

   As a workaround, I tried to run it over 200 users and put a wait 
command after 200, then run 200 again , wait, run 200 again. I found out 
that, there after running the first 200 users, it will pending for 
nothing. When I do a ps, I found out there are always a few processes 
never finished. 

   I am not sure whether this is related to Perl and memory leak 
problem. But somehow it is coincidence with the problem describe below.
   Any clues??
