      A timer that is shared across all channels in a group did not stop when one of the channels was closed. If OOB
      messages were passed around at the time a channel left a group, messages were added to the Retransmitter after
      the channel closed. This happened because a message was added after Retransmitter.reset() and caused retransmission requests for previous messages. This issue is resolved by fixing the condition
      that caused retransmission requests when a message from a node is processed at the same time the node leaves

    Description

      Sometimes, messages are being added to the Retransmitter after a channel has been closed. This can happen if OOB messages are being passed around at the time a channel is leaving a group. The problem occurs in that messages are added after Retransmitter.reset(). Normally, the timer is also stopped when the channel is disconnected, but since the Timer is shared amongst all channels, any messages added to Retransmitter after reset() just continue to be requested because the timer that those tasks were scheduled on did not die.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
