How much memory does your allocation total plateau at?
How do you know that it's exhaustion of memory that's getting you killed?
I assume (you don't say) this is iOS, and that your problem is showing up on
the device. What does the device's own log show?
Is your app in the foreground or background at the time?
Use the VM Tracker instrument and see if you're eating up memory in other
zones. In my experience, your application heap (Allocations) can be stable, but
if you accumulate Core Graphics/Core Animation buffers, you're in trouble
pretty quickly. By default, VM Tracker snapshots the heaps only when triggered
(Snapshot Now). It may be better if you check Automatic Snapshotting in the
detail area for VM Tracker.
