Using code adapted from the example in the docs (https://docs.python.org/3/library/multiprocessing.html#using-a-remote-manager), if you create a remote queue server, a producer which puts items in the queue and a consumer which consumes elements from the queue. If the consumer gets killed and restarted again, it misses one item from the queue. For a reproducable example see the stackoverflow reference below.

Expected: items stay in the queue until a consumer consumes it
Happens: one item still gets consumed from the queue even if after a consumer gets killed

Version: Python 3.6.0
