@pyricau Good job! I’ll remove my hprof file from the web by the end of the week: please make a copy of it if needed.

Thanks!

I need to find time to look into that. Here’s what I’d do, if someone is interested:

Open the heap dump with profiler on to check the memory footprint and confirm it’s out of the ordinary. The logs indicate only 11Mb left, so figure out what exactly took all the space.
Open the heap dump with Android Studio as well as YourKit, to see how these behave.
