Forge 41.1.0 crashes on Startup "User limit of inotify instances reached or too many open files" error

[quackityys]

Installing Forge 41.1.0 on Docker with Java 17.0.1. Installer installs correctly Minecraft launch crashes. I tried to increase the open file limit in /etc/security/limits.conf and it didn't fix the Problem.

Forge 39.1.0 worked fine using the same setup with Java 17 and Docker.

 

Here the screenshot of the startup:

 

The server installed successfully
You can delete this installer file now if you wish

You have hit an OS configuration limit.

From the error message it looks like this one or it might be max_user_watches?

$ sudo sysctl -n fs.inotify.max_user_instances
128

How you change it will depend upon your distribution, but it is probably /etc/sysctl.conf?
