Dear Monks,
I have a problem somewhere in my system that I can not figure out and am here to seek your help. I am running my perl script on an Apache server. The perl script invokes an external program and every second gets a response back from this external program telling it how many percent of the job has been completed among other statistical data. The script then pushes these data to the client machine running Firefox. It usually runs to completion most of the times but once in awhile, especially on a long running job, it just died in the middle of the runs but no error message is displayed on the client machine's window. The external program no longer existed when I type in ps -aux. I looked thru the Apache error_log in /etc/httpd/logs but found nothing in there. If I run the external program manually, everything is fine so the problem is not with the external program. Any help would be appreciated.
Attached is part of my code but the problem might not be with the code though.
Thanks in advance for your help.
  print "Content-type: multipart/x-mixed-replace;";
  print "boundary=magicalboundarystring\n\n";
  print "--magicalboundarystring\n";

    $com = "./myapp 5000";
    open PIPE, "$com |";

    while ($data = <PIPE>)
    {
        my ($read, $write, $update, $complete) = split(/::/, $data);
        print "Content-type: text/html\n\n";
        print "Percent completed: $complete\n";
        print "Write Time: $write\n";
        print "Read Time: $read\n";
        print '</body>';
        print '</html>';
        print "\n--magicalboundarystring\n";
    }
    close(PIPE);
