Weird memory issue on Samsung Galaxy Note
<p>My application crashes on the Samsung Galaxy Note, apparently due to memory issues.  The weird part is that my app does not appear to be using a particularly large amount of memory at the time of the crash.  However, according to the logs, the OS seems to think that memory is running low and starts killing all active processes (including my app).  I don't see this behavior on any other device I've tried (test devices include: Acer Iconiatab, Samsung Galaxy Tab, Droid3 phone, Nook color, LG Optimus V).</p>

<p>My suspicion is that this is related to the android build included on the device, maybe it does something funky and wrong in handling low memory situations.  Any ideas about what could cause this sort of behavior, or suggestions about how I can rectify it?</p>

<p>The garbage collections log immediately prior to dying, shows moderate memory usage (I know that these are from my app based on the PID):</p>
