Hello,

We have a strange issue on one of our systems that we just can't seem to figure out.  We loaded in 5000 records yesterday and have not loaded any since then into our brokers.  Examining the logs for the brokers, we confirmed that no data has been sent to those topics since we did the load yesterday.  However, since the data load yesterday, we've had the same record show up in our consumer logs 5 times.

Offsets have been checked (We log everything INFO and above by default) and it doesn't look like that the consumers are reading from an older offset.  The only thing that I see that may cause this issue is a broker that sometimes is accessed by the consumers, but not all of the time.  It's an older broker that we don't use anymore for our project, but is still there for another project.  Until this morning, it did have the topic we were reading from on the broker.  I did remove the topic by deleting the directories and restarting the broker, so hopefully the consumers don't try to use it again.

Could that be why we're seeing the duplicate records?  Or is there something else we need to check for?

Casey
