Public bug reported: Since upgrading to Ubuntu 24.04 I have been seeing `Failed to add a watch for /run/systemd/ask-password: inotify watch limit reached`. Even when I added `fs.inotify.max_user_watches=1048576` to `/etc/sysctl.conf`, I would still get the error and `cat /proc/sys/fs/inotify/max_user_watches` always returned 65536.
After some investigation I found that `/usr/lib/sysctl.d/30-tracker.conf` sets max user watches to 65536. This setting is loaded after the setting in `sysctl.conf`, which caused my confusion. Notably, this limit is fairly low for modern systems, see this post in which common software like VSCode needs almost 10x as many: https://github.com/torvalds/linux/commit/92890123749bafc317bbfacbe0a62ce08d78efb7 ** Affects: tracker-miners (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to tracker-miners in Ubuntu. https://bugs.launchpad.net/bugs/2085166 Title: inotify watch limit set too low by tracker Status in tracker-miners package in Ubuntu: New Bug description: Since upgrading to Ubuntu 24.04 I have been seeing `Failed to add a watch for /run/systemd/ask-password: inotify watch limit reached`.
