SHARDS_LEFT_ON_TERMINATE_CWOBJ1129=CWOBJ1129W: Some of the shards were not removed before the container terminate completed on {0} container. Shards left: {1}
Explanation
A call to terminate the container attempted to destroy all of the shards on the container, but shards still remained on the container. A shard destroy could have failed or a new shard could have been placed during the terminate. Any shards placed on the terminating container will be failed over to other containers.
