I'm unable to reproduce the your issue of multiple processes when
invoking start multiple times. Did you delete your
script/backgroundrb file and run rake backgroundrb:setup?

I use capistrano and have added the following tasks to my
config/deploy.rb for handling the thrown error where a pid file
doesn't exist.
task :restart do
run "mongrel_rails cluster::restart -C #{mongrel_conf}"
restart_backgroundrb
end
task :restart_backgroundrb do
begin stop_backgroundrb; rescue; end #this catches the bdrb error
where a PID file doesn't exist
start_backgroundrb
end
task :stop_backgroundrb do
run "#{deploy_to}/current/script/backgroundrb stop"
end
task :start_backgroundrb do
run "#{deploy_to}/current/script/backgroundrb start"
end
Good luck!
Jonathan
