ENOSPC error

I ran the Yeoman generator to create a Keystone website to play with. The website works well, it’s just that a few minutes after I run node keystone.ks, usually at one of the first requests, it prints out the error listed below and then it dies. For the moment, pm2 keeps restarting it every time, so it works, but it’s clearly not the best option. Do you have any idea what I could do to make Keystone.js stop running out of memory?

Thanks!

I had the same issue running Keystone with nunjucks on CloudFoundry (where max_user_watches is as low as 8192 and I don’t think can be changed)

My workaround was to disable nunjucks watch with nunjucks.configure(undefined, {watch: false});

in keystone.js file.

Maybe that could be an improvement to automatically setup nunjucks that way in production env

This seems to have answered the question, so I’ll close this issue! Thanks for jumping in @KuroTsuto and @bpavot!
