Subject [jira] [Comment Edited] (CB-7660) Cordova iOS File-Transfer download memory leaks

----------------------------------------------------------------

I am also experiencing problems while downloading multiple files via FileTransfer (0.4.8)
on an IPad2. I am using cordova 4.1.2, and File (1.3.2).

Memory consumption rises continuously, eventually leading to a memory warning, and further
to the app crashing.

[EDIT] I've just tested the FileTransfer again with 1000 dummy (txt) files à 200KB.
While processing file list:
- CPU: 120-130%
- Memory: 60MB rising up to 89MB
- Network: 200KB/s

There is no crash, and Memory stays about the same til the end. However, after all files were
downloaded, I would like the Memory to decrease again? Memory stays at 89MB afterwards.

Is there some way of freeing the Memory consumed during FileTransfer?

I'll continue testing ...
