MEGAsync crashes for specific folder when trying to start sync: Unable to add filesystem watch

[joachimrs]

If I delete the folder and make a new empty one and "Add" a sync, it crashes, too. Something about Filesystem Watch. Do I need to tweak some kernel parameters as I might have some lots of files here...

Check you fs.inotify.max_user_watches via
cat /proc/sys/fs/inotify/max_user_watches
if it is 65535 it might not be high enough.
Changing the value in /etc/sysctl.conf or a /etc/sysctl.d/##-megasync-inotify.conf file will help.
There should be a /etc/sysctl.d/99-magesync-inotify-limit.conf which sets
fs.inotify.max_user_watches = 524288
which is the max value.
sysctl -p
loads the new configuration. This works on Linux Mint 21.2. On LMDE6 I had to put the line into /etc/sysctl.conf and it does not seem to persist between reboots. Will investigate further.
