No idea; can you grab /proc/slabinfo and /proc/meminfo every minute or so until it oom kills trinity? Maybe that will give us a hint of at least where the memory is getting consumed. It could be the extent status tree cache, for which the need for a better shrinker is a known bug that we're working on, but that's just a wild guess.
