largest single allocation? when you say single, do you mean one
NSMutableData object?
I put a debug tracker on the length of the NSMutableData object and
the largest value it got to before crashing is 745316412. Is that
+-745MB?
Is there a way to remove used bytes from the earlier part of the
buffer (the bytes that were appended earlier)? It's not possible
for me to release the buffer since another thread is reading off of
the buffer in a slow pace. I was wondering if the reader can take
off the bytes it has read (so the buffer wont reach near a GB that
fast)?
To me it sounds like memory mapping a file may make more sense for
what you appear to be doing or a ring buffer (not knowing you exact
usage model).
