DMS : Replication Task is in 100% running state, but stopped replicating data in between. Source - RDS, Destination - S3.

DMS replication task, which has source as RDS - MySQL and destination as S3, it is ongoing cdc replication task and is showing status as runnning 100%, for 4 hours it was not replicating any data, when we checked RDS, it was having new data of those 4 hours, so why did DMS didn't and also didn't put error status.

Later we just stopped and resumed, 3-4 times and then after 3rd attempt data started coming from 4 hours before checkpoint.

This issue has happended for our omnifin database (comparitively big Db, issue happened for the first time) and for knab database (very small Db, on every 27th day of the month this issue happens)

So why does DMS without showing any error, stops performing its replication task, and in status it is green with runnning 100% display.

Please look into this issue.

Thanks.
