Thanks! That was indeed my problem. Being new to Objective-C, I tend to run into these problems. Strange that it only happened on small data sizes and not the big ones.

Thanks again,
David

getData() returns a char *
getDataLength() returns an int

The "data" ends up being of size 0 bytes. If the size of the data I
pass in is greater than 16KB, there is no problem. Unfortunately, I may
have data sizes smaller than 16KB. Has anyone ran into this problem,
and do you know of some way around it, or perhaps I'm doing something
wrong?

*NEVER EVER* separate alloc and init to two different lines. That's the culprit -- init returns a different object (which it can do any time, and for class clusters it of course does indeed).
