While doing a demo of my new side project my local replica began to crash (:grimacing:) and the issue according stacktracke does not seem linked to my code. Any clue what’s happening and why I land in that state? ❯ dfx start Running dfx start for version 0.12.1 Using project-specific network ‘lo…

internal_error: “Too many open files (os error 24)” Seems like we need to increase the number of max open files in the OS: launchctl limit maxfiles sudo launchctl limit maxfiles <new soft limit> <new hard limit>
