Are you sure that you are not just running out of memory on whatever iPad you are testing it? If you fill up the RAM memory, your iPad crashes and that's quite normal...

i can see memory usage while testing and it crash due to lack of memory. also smaller zip files can be downloaded and unzipped. is it normal to crash due to unzipping 50mb file?
