crashed with assertion in bucket_engine - bucket_engine.c:831: get_engine_handle: Assertion `es' failed

Issue reporter had an unexpected system crash. Log messages show a lost ns_port connection followed by a bucket_engine assertion.

Bug reporter had done a delete through telnet earlier (presumed to moxi) and had deleted and recreated the default couchbase bucket 10 hours earlier (It was only running for 10 hours).

There appears a lot of time in between, but doesn't according to the log messages. That's a bit hard to interpret. Will ask bug reporter to send in more information.
