Comment 6 for bug 1240203

/etc/sysctl.d/30-nepomuk-inotify-limit.conf -- I do not have such a file.

but `cat /etc/sysctl.d/*.conf /etc/sysctl.conf | sudo sysctl -p -` gives

error: "Invalid argument" setting key "fs.inotify.max_user_watches"

as well as

error: "kernel.maps_protect" is an unknown key
error: "sys.kernel.maps_protect" is an unknown key
error: "net.ipv4.ip_always_defrag" is an unknown key

well, `grep fs.inotify.max_user_watches /etc/sysctl.d/*.conf /etc/sysctl.conf ` gives

/etc/sysctl.d/30-spideroak.conf:fs.inotify.max_user_watches = 65536
/etc/sysctl.conf:fs.inotify.max_user_watches = 524288

The last one looks odd.

Well, no values in range 8K..512K meet the need :(

After commenting out *all* the erratic lines, it was made to work finally.
