- Thread-topic: Crash on wake from sleep - mmap issue?
This crash is when trying to read from a file (130mb) that has been mmap'd.
It only happens rarely, and only when waking from sleep, but happens on both
10.8 and 10.9. It is almost like the mmap memory is not available right when
the system is woken up
Any ideas?
