The bug report the agent sees
Redis-backed workers can become unstable or stop consuming tasks after broker connection loss and reconnection.
When a Redis connection is dropped, the transport may leave invalid or already-closed sockets registered with the event loop. This includes sockets with no usable file descriptor, missing sockets, and subclient sockets. The worker should remove these dead registrations without raising polling errors.
A reconnect can also race with cleanup from the previous connection. In that situation, the worker may remain alive but lose the callback that starts polling for Redis work. No tasks are consumed even though the worker responds to health checks, and messages accumulate in the broker. Reconnection cleanup must not disable polling for the newly established connection.
Repeated reconnects can leave multiple obsolete timer entries behind. As a result, timer callbacks run repeatedly and redundantly for old connections instead of only the current connection.
If restoring visible messages or checking Redis subclient health encounters a connection failure, the timer callback currently allows the exception to reach the event loop. The worker can then tear down and repeatedly restart its event loop. These transient failures should be skipped for that timer invocation so normal polling and later retries can continue.
During channel shutdown, restoring unacknowledged messages can race with task completion. A message may be acknowledged after shutdown begins but before its restoration is attempted, causing the broker to report that the message no longer exists or is unavailable. This expected race should not produce restoration errors or make channel shutdown fail when the message has already been acknowledged. This is a separate bug in the virtual transport base's unacked-message restoration, which every virtual transport uses when a channel closes; it is not the Redis transport's periodic restore described above. When restoring a message raises, the error must be recorded only if that message has not been acknowledged since the flush at the start of the restore ; a message acknowledged in the meantime is dropped from the unacknowledged set without an error, while failures for messages that were never acknowledged are still returned to the caller.
Contract for cleaning up after a dropped connection (what the tests observe on the poller's disconnect handling): if the dropped connection still has a socket object or a raw integer descriptor, that same object is removed from the event loop exactly once, and its entry leaves the poller's descriptor-to-channel registrations only when a valid descriptor is known (`fileno()` of 0 or more, or the raw integer itself); when `fileno()` returns -1 or raises, no registration is removed, because that descriptor may already belong to another socket. If the connection has no socket at all, nothing is removed from the loop; instead every registration whose channel's `client` or `subclient` is backed by the dropped connection is dropped, and registrations belonging to other connections stay. The channels in those registrations expose `client` and `subclient` as ordinary attributes and may be lightweight objects without a populated instance dict. All of this holds whether or not the loop currently tracks any descriptors, the handling never raises, and the per-tick polling callback stays registered on the loop. The poller object the transport is registered with may support nothing beyond its descriptor set, its descriptor-to-channel mapping and its callbacks: the transport's own disconnect handling must perform the loop removal and the pruning itself, must not read poller attributes that nothing has set, and must not rely on a disconnect method of the poller doing the work (it may be inert); any per-registration state such as timer handles has to be kept by the transport's own code.
Contract for the periodic maintenance callbacks: each invocation attempts its operation exactly once (restoring visible messages on the channel with active queues; the health check on a channel's cached subclient), and a failure is swallowed for that tick only when it is an instance of one of the classes listed in that channel's `connection_errors` attribute, which may include classes that are not redis-py errors, so a fixed exception class is not sufficient. Re-registering with the event loop after a reconnect cancels the timer entries of the previous registration (the handles the loop's `call_repeatedly` returned for it) and leaves the new registration's entries live: after three registrations, each entry of the first two sets has been cancelled exactly once and the third set is untouched.

Connection String
=================
Connection string has the following format:
.. code-block::
redis://[USER:PASSWORD@]REDIS_ADDRESS[:PORT][/VIRTUALHOST]

To use sentinel for dynamic Redis discovery,
the connection string has following format:
.. code-block::

Transport Options
=================
* ``sep``

simulate Acknowledge of AMQP protocol.
