Real device app crash on uploading files due to memory leaks

[GaraGentor]

Whats my Problem:
The app crash while uploading serval files with some mbs. The total size of all files is 2,8gb. The app crashes due to a memory issue. Tested on a real iPad with 2 gb of memory. The files are pdfs.

What I have tested:
1.
I tried to upload file after file and the memory of the device stacked after each file, the size of the file itself. So it crashed on the 30 file because my iPad hadn't that much memory space left.

I also tried to upload all Files at once. The App crashed instantly because the memory of my device was instant full.

I also tried to reinitialize RNFS and nullified the existing one. But the memory does not shrink to its original size. In that case my app always will crash after doing some uploads.

Enviroment:
react: 16.6.3
react-native: 0.57.8
react-native-fs: 2.13.3

I'm currently struggling with the same issue. Using the RNFS.read() method in a loop doesn't release the memory for some reason. There's a linear growth in memory usage with each read/uploaded file chunk.
