in reply to forking, no child waiting.

system("cmd &"); works for me....

Update sorry, to be safest
system("cmd > /dev/null &");
just to make sure it isn't waiting on output from the system command

    You know, that has worked for me in the past, but not in this case, I have tried system() exec() and fpassthru(), and now recently pcntl_fork(). This perl scripts gets angry when php leaves it alone for some stupid reason. Another thing I am thinking might work for these situations, is to have the first script write a cron job to do the second script, and then the second script will always remove itself from any cron entries, but I am hoping for a simpler solution, if Perl can fork, or whatever.

      Hrm... yeah... try putting this in the perl script you are calling... 
      fork && exit(); #background process
close(STDOUT);
close(STDERR);
close(STDIN);

      see if that detaches it... now you should not need th > /dev/null &

        Oh man,,,,

        I was all happy, and then I tried it, it worked great when running it from the prompt, but still just kind-of dies when done from the php app. I am hating this part! Here is where I am calling my perl script: 
        $run="snmp-wdr -c mrtgtest $request &";<BR>
echo "<BR>COMMAND SENT: $run<BR>";<BR>
$setsys=system($run);<BR>
