I am trying to launch a lengthy process in response to a user request. I have tried doing it by the backtick operator in a usertag. The process seems to get aborted after a few seconds. here is a snippet of my usertag: UserTag cmd-gen-download Routine <<EOR sub { `perl /usr/local/psa/home/vhosts/mysite/lengthy_script.pl`; return; } EOR Does anyone know why it is getting aborted. Thank You Chaim Klar
