A Ruby on Rails application running under Passenger 2.2.7 crashes during a post destroy operation. The failure originates in the Post model's delete_meta_data callback at line 234, which invokes MongoDB's collection.remove via mongodb-mongo gem 0.14.1. The stack reveals deep transaction handling with plugins like seamless_database_pool and deadlock_retry, terminating in Passenger's spawn server process.
