Make sure your actions aren't going to hang up for excessive amounts of time, or the manager process will attempt to replace it (possibly causing your excessive forking). See https://metacpan.org/pod/Mojo::Server::Hypnotoad#heartbeat_timeout (defaults to 50 seconds)
Make sure you are invoking hypnotoad using its full path, and that it is the hypnotoad installed for the same Perl you've installed all your dependencies to. Make sure you are using a fork safe database connection manager like DBIx::Connector or Mojo::Pg, and not attempting to share any live database connections across forks (e.g. the body of the Lite script will run in the manager process before workers are forked from it - request handlers should retrieve a new connection from your connection manager so they can connect anew if needed). -Dan On Thu, Nov 19, 2020 at 4:57 PM Joseph Fridy <jmfr...@gmail.com> wrote: > I have recently transitioned from solo development to beta testing for a > Mojolicious::Lite application.
