EMFILE, possible file handler leak

Open tlhunter opened this issue 3 years ago • 0 comments
Bug Description When running local builds over and over (bundle exec middleman build), I eventually get an EMFILE error. I can temporarily fix this by closing VS Code and dev servers that watch the filesystem for changes before rebuilding. However, even with them closed, I'll eventually get the error again after compiling several times. This makes me think each time a compilation happens that there are still filesystem handlers left open.
