I stopped watching after hanging the browser for 30 minutes. Mongrel calls reap_dead_workers for 3 different reasons: too many open files (lines 651 & 746), max processors (734) and graceful shutdown (688). Graceful shutdown gives workers 60 seconds to finish, then kills them. Too many open files should only happen if you have a large number of requests or some other process on the machine is eating up file handles. Max processors can be set when calling HttpServer.new, but defaults to 1 Billion (2**30 - 1). Keep in mind this is all on mongrel-1.0.1. I haven't looked through the code for later versions.

I see the TimeoutError raised in the reap_dead_workers function (mongrel.rb:665) in our logs occasionally when there's a backup. Doesn’t mongrel have a default 60 second timeout for all actions?
