I tried echo 524288 | sudo tee -a /proc/sys/fs/inotify/max_user_watches but it didn’t help. i guess i’ll have to spend the time here - https://facebook.github.io/watchman/docs/troubleshooting.html#poison-inotify-add-watch btw, I am on ubuntu, not mac.

if anyone got a quick solution, please comment here.

watchman shutdown-server

the last command solved it.

Does anyone have a permanent solution for this?, I did use the following command and it works fine, but every time i restart my pc it resets the values.

I have tried editing the maximum queued file itself but i again it always resets. I am running a Ubuntu 16.10.

@dennisobel use “react-native start” in the root of your project and then (in other terminal) “react-native run-android” or “run-ios”

@AndreiCalazans on Ubuntu 16.04 (not sure about 16.10) the value of fs.inotify.max_user_watches in /etc/sysctl.conf needs to be changed and then run watchman shutdown-server && sudo sysctl -p for a permanent fix.
