Typically by the time you know what they are and where to find them, you won't need to know where to look in the first place. -noshell & -noinput prevent you from interacting with the erlang console http://www.erlang.org/doc/man/erl.html -os_mon are all parameters about whether to start up a supervisor hierarchy to monitor memory, cpu, disk etc in the vm and/or OS. http://www.erlang.org/doc/man/os_mon_app.html For these types of things I like to run erlang interactively (dump the -noshell -noinput crap) and launch couchdb -i, if thats on debian, and pray for enlightenment when the error messages come past again.
