Truss is unlikely to reveal anything -- your pmap output (assuming
it was taken just before the failure) shows *nothing* that would
have prevented further brk() growth.

One other suggestion: try running the app with libmapmalloc (via
LD_PRELOAD) -- it may be able to bypass whatever limit you are
bumping into, or at least provide further clues.
