event overflow warning when adding large number (1000) of web files

Warning 'Ignoring event overflow' [1] when adding 1000 files at one.
Steps to reproduce
1) Create a folder named 'large' in the web files space
2) Add 1000 files
Expected: 1000 files added
Actual: 4 files added and warning.

Moving the folder to a new name throws: java.lang.OutOfMemoryError: Java heap space

To consider if these kind of problems must be logged as error instead. For the developer it can make it hard to use and track what's synced and what not
