I am having this error on multiple folders when I enable the watch changer in the advanced settings of a folder I add:
failed to setup inotify handler. Please increase inotify limits, see https://docs.syncthing.net/users/faq.html#inotify-limits
I have followed the faq and I logged into the linux command and add up to 1,000,000 and it is still doing this. I have even restarted syncthing and I am still having a problem. Please note, I have this running inside of Docker using Portainer. I have this running on other NAS using Docker and Portainer and there are no issues with this error at all.
