   > Is there any chance those are related to this change?
   
   Yes, it was related to this change. We improved the performance of produce so drastically that the MirrorSourceConnector started to throttle offset syncs due to the change in KAFKA-14610. This caused the initial 0:0 offset sync to get skipped, which prevented a checkpoint from being emitted, which caused the test to time out.
   
   I've adjusted that test to perform a non-zero-offset commit, and wait for that sync/checkpoint to be emitted before proceeding with the rest of the test normally.
