For anyone that is submitting data to #heliboard. We found a bug in creating the zip files. It starts to hang for quite a long time, and can sometimes crash, if you try to submit several thousand gestures. We are working on it.
My guess is we are compressing too aggressively, and Java's zip implementation is RAM heavy.
In the meantime, we suggest you keep your submissions to fewer than 3,000 words.
Your mileage may vary based on the speed of your phone and the amount of RAM it has.
