I have a process that is uploading images. My issue is as following,
when uploading a large number of images and my application does not
have focus, memory usage continues to climb until it is maxed out,
causing the app to hang/crash. On the other hand, if the app has
focus and the user clicks anywhere in the app, memory is released and
memory usage stays low. While this is occurring in the main thread,
the actually connection work is being done in a separate thread (via
ConnectionKit). The action of the user clicking in the app appears to
trigger an interrupt, allowing memory to be released or the main
thread to manage its autorelease pools. Couple of questions:
1) Why is the main thread not managing the autorelease pool(s) without
this user interrupt?
2) Is there a way to trigger the main thread to cleanup its
autorelease pools?
3) If not, is there a way to simulate the user click or trigger the
same underlying reaction to it, programmatically?
4) Am I completely off base with my hypothesis?
Thanks,
Chad
