It sounds like the bug in fuser was that an earlier version forked but then was never reaped upon completion, leaving thousands of fuser processes in a zombie state consuming memory, which leads to a server crash. I think that has already been fixed in the version of psmisc that I'm using.

Memcached is certainly an option, although it would have to be a separate pool from our main memcached instance, otherwise sessions would be getting randomly evicted from our cache pressure. I'm not convinced that deleting 14,000 files should take 25 minutes, though. That sounds way too slow to me. I'm going to wait a couple of hours and see what the performance of a simple rm is like.
