Running PyMongo's test suite, on the branch where I'm implementing sessions, I crashed a standalone mongod running with auth.

Log attached.
I think that PyMongo was executing some part of this test:
def test_aggregate_raw(self):
c = self.db.test
c.drop()
docs = [{'_id': i, 'x': 3.0 * i} for i in range(10)]
c.insert_many(docs)
batches = list(c.aggregate_raw_batches([{'$sort': {'_id': 1}}]))
self.assertEqual(1, len(batches))
self.assertEqual(docs, decode_all(batches[0]))
PyMongo's aggregate_raw_batches method sets the initial batch size to 0 with the "aggregate" command, then issues a "getMore".
