I think my problem only occurs when ran from inside a\r\nsetInterval. If I simply load 150 images sequentially into an\r\nimageview's image, then only 15 MB of real memory is used. However,\r\nwhen performed inside the setInterval's callback, the real memory\r\nusage escalates to nearly 60 MB if 100 images are used, and up to\r\nabout 100 MB if 150 images are used. It will stay at that level\r\nthroughout subsequent loops until the app is shut down. I obtained\r\nthese numbers by running Instruments with Activity Monitor.

\r\n

I have attached a sample project with the relevant 10-12 lines\r\nof code in the app.js file and 100 images of 20 KB each.

For quick reference, here are the relevant lines of\ncode.

Assigned this to Kevin, since he's the one who asked for the\nticket on the Q&A.

Thanks for creating the test case, that's very helpful.

I assume no one's had a chance to look at this?

Since I'm not a paying customer, I certainly have no right to\ncomplain. But my inability to get answers here or in Q&A tells\nme I need to abandon the Appcelerator platform.
