I can confirm this issue. I happens every time when elisa is run.
```
Inotify Watch Capacity Low
Your open applications want to watch too many files for changes! When the
capacity is exhausted it will prevent further file monitoring from working
correctly. Either close some applications or increase the limit. Currently
using 25% of instances and 98% of watches.
<button>Increase Watch Limit</button>
```
Increasing the limit via the dialog (see attachments) helps to solve the
problem. With `inotify-consumers` it is possible to list the applications that
use inotify. Elisa uses over 100k monitors and the number keeps increasing.
```
$ bash /tmp/inotify-consumers

Elisa uses 100% CPU while setting all these watches. After running for a few
minutes, the watch capacity needs to be increased again. At this point the
number of watches is 123674. Increasing the limit more does not create more
watches. The limit is at 124304 (`cat /proc/sys/fs/inotify/max_user_watches`).
Since elisa has taken all the available inotify watches, other applications
cannot set any watches.
Closing elisa frees up the watches.
