Thanks guys for the help.  I find it a little hard debugging but those
links helped a little.

Could someone consider the following numbers to be too high to make
the app easily crash?  Cause as of now at this point is when it
crashes.

ID | Heap Size | Allocated | Free | % Used | # Objects
1       3.570 MB        2.702 MB        889.195 KB      75.68%  49,041

Thanks!
