The above is great help. However, I am trying to use `start_server` with `plackup` options and getting the following error

$start_server --port=5000 --pid-file=pids/app.pid --status-file=status/app.status -- plackup -s Starman -w 10 -E production -D -a ~/Sites/blog/bin/app.pl
start_server (pid:4453) starting now...
starting new worker 4454
new worker 4454 seems to have failed to start, exit status:0
starting new worker 4461
new worker 4461 seems to have failed to start, exit status:0
starting new worker 4468
new worker 4468 seems to have failed to start, exit status:0
starting new worker 4475
^Cworker 4475 died unexpectedly with status:0, restarting
starting new worker 4482
received INT, sending TERM to all workers:4482
worker 4482 died, status:0
exitting

and, in spite of the above, it seemed to have started several starman master processes. That is not what I wanted.

$ps -ax | grep 'starman master'
 4455 ??         0:00.01 starman master           
 4462 ??         0:00.01 starman master           
 4469 ??         0:00.01 starman master           
 4476 ??         0:00.01 starman master           
 4483 ??         0:00.01 starman master           
 4496 ttys001    0:00.00 grep starman master

of course, the bare plackup command works fine

$plackup -s Starman -w 10 -E production -D -a ~/Sites/blog/bin/app.pl

The above starts only one master and 10 workers.

Suggestions?
