It looks to me like you had trouble shutting down because you were in the middle of a HUGE transaction.. having been killed, a rollback of nearly 10 million statement need be run.
I would suggest that somewhere in your processing, you are holding one connection open a long time, doing a lot of work, but failing to commit it periodically.
