Unicorn/Nginx process missing, socket open

ruby-on-rails-3.1 nginx capistrano production-environment unicorn

Still not sure how this happens, but the following solution seems to work:

lsof /tmp/my_app.socket - lists the pids

kill -9 pid - (replace 'pid' with one of those listed)

Then cap deploy:start from the local terminal.
