Thanks for reporting it in! It seems I enthusiastically chose a larger buffer size that appears to be having some issues on some devices that have a lot of memory pressure. If you reboot your phone, as awful as that sounds, it will likely fix the issue. EDIT: I've just submitted an update to Apple that uses a more conservative buffer size. This aspect is hard to get right: I once used an adaptive buffer size that heeded to memory warnings, but that meant that the buffer filled to lower levels than a conservatively sized buffer. If only iOS had an opt-in for an *alloc returning 0 instead of these warnings, or at least notifying us of how much space left before we're SIGKILL'ed.
