Hi All, I take the data from user and tell the user that result will be emailed.
On the server side I process the data . For processing I have made a small perl script which breaks the data into multiple small segments and process them in using system command 
$command ="nice R --slave --args $DirName $SubDirName < read_parameter
+s_by_file_batch.R ";
system($command);

[download]

System calls R till the main cgi script is alive. I can see cgi as defunctional using top. Once cgi dies system command doesnt gets executed
Last few lines of main cgi script are
    $cmd = "perl /var/www/cgi-bin/vcgi/ProcessFiles_test.pl $UploadDir
+ $DirName $TotFiles &";
    system ($cmd);
    fork && exit;

Can anyone please suggest how to overcome this situation thank you
