### Steps to reproduce

Having a couple of AutoUpload folders, with a lot of files to sync.
There is also a large number of conflicts during the sync.

### Expected behaviour

The files should be uploaded after some time, except for the conflicts.

### Actual behaviour

### Cause of error
```java
Exception in thread "Thread-96" java.lang.OutOfMemoryError: Failed to allocate a 24 byte allocation with 1475504 free bytes and 1440KB until OOM, target footprint 268435456, growth limit 268435456; giving up on allocation because <1% of heap free after GC.
