The error of "Error adding inotify for /public_html/sites/default/files/php/twig/ ... No space left on device" caused by no more inotify available in your system. Quiet simple to solve this issue, just increase the inotify value. But problem will be hard if you use Container for VPS, you need Server Administrator to alter inotify value.
Suppose your inotify is 8192 and you want to increase to 128000:
- # cat/proc/sys/fs/inotify/max_user_watches
- 8192
- echo 128000 > /proc/sys/fs/inotify/max_user_watches
No need to restart VPS/Server, HTH.
