function system

I have a problem with the function system.
I execute a source like this:
programa.pl
#!/opt/perl/bin/perl
.
.
.
.
.
.
.
sub funcion_monitor ()
{
          ................
          ................
          system("nohup funcion_halt &");
}

sub funcion_halt ()
{
         system("programa.pl stop");
         system("UNIX's command");
         system("UNIX's command");
}
system("programa.pl stop");
sub funcion_parar ()
{
         ..................
         ..................
         system("UNIX's command");
}

when I run the function "funcion_monitor" this call to
the function "funcion_halt" - it using the perl's
function system and the UNIX' command nohup.
The function funcion_halt call again to my programan
with argument stop ( funcion_parar ). The function
"function_para" run without problems, I haven't errors
when I execute the program from command line -
./progrma.pl -, but when I use the same source in a
cluster the two lines after "system("programa.pl
stop"); doesn't runnig. I understand nothing.

There are some problem with the command system in this
case?


Thank for all
