1) If a command gets aborted, it remains in "IN_PROGRESS" state on the agent. Agent sends it in each heartbeat until agent gets restarted.

2) Because of an ordering issue in the heartbeat report processing, server sometimes mismatches command statuses. (If we have COMPLETED command and ABORTED in the same heartbeat, it may think that completed command was aborted and rejects state change). This situation was rare previously, but because of the first issue aborted commands come in each Heartbeat.
