This is your web server killing them off..

It is correct operation, but I'd suggest your web server config needs
tweaking to significantly increase the interval between killing off
Alternately (and more recommended), would be to run the fastcgi in
'external' mode, so that you start your myapp_fastcgi.pl entirely
independently from the web server, and it manages the processes,
rather than your web server being able to start and stop the
application whenever it likes.
