Check the current file watch limit, default is usually 8192. cat /proc/sys/fs/inotify/max_user_watches Set new max_user_watches. sudo sysctl fs.inotify.max_user_watches=32768 sudo sysctl -p Make the changes permanent. echo fs.inotify.max_user_watches=32768 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p References:. To increase the inotify limits permanently (across reboots), you can set the values in the configuration file /etc/sysctl.conf. For instance, adding the following lines to set the maximum number of watches to 524,288 and the maximum number of instances to 1024: fs.inotify.max_user_watches=524288 fs.inotify.max_user_instances=1024. If default number of inotify watches is non-sufficient to have MiniDLNA monitor all your media folders, increase inotify watches through sysctl (100000 should be enough for most uses): # sysctl fs.inotify.max_user_watches=100000 To have it permanently changed, add to /etc/sysctl.d/90-inotify.conf.

We should change this config value in similar methods. Change sysctl.conf in host machine not containers. sudo nano /etc/sysctl.conf Add fs.inotify.max_user_instances = 1100000 to the bottom of file and save changes.

To prevent this situation it is recommended to increase the watches limit (to, say, 512K): Add the following line to either /etc/sysctl.conf file or a new *.conf file (e.g. idea.conf) under /etc/sysctl.d/ directory: fs.inotify.max_user_watches = 524288 Then run this command to apply the change: sudo sysctl -p --system. he user limit on the total number of inotify watches was reached; increase the fs.inotify.max_user_watches sysctl\n'. There are a limited set of values you can change via docker run --sysctl but these do not include the inotify values. The only way to change this value is to run sysctl, as root, on the host, outside of Docker.
