Describe the Bug

In transaction message scenario, the first time execution result was UNKNOW. We expected to receive broker's check request later, but did not.

Steps to Reproduce

1. Startup server in proxy cluster mode
2. Startup a remoting TransactionProducer
3. Sleep 5 seconds before sending one transaction message, and return UNKNOW in TransactionListener#executeLocalTransaction
4. Keep TransactionProducer running and don't send more messages
5. Observe whether TransactionListener#checkLocalTransaction will be called

What Did You Expect to See?

TransactionListener#checkLocalTransaction will be called

What Did You See Instead?

TransactionListener#checkLocalTransaction has not been called

Additional Context

No response

[redlsz]

Transaction log indicates that the broker cannot find producer channel when trying to call client CheckTransactionState.

In this case, the producer send message before its first heartbeat, which causes offline misjudgement when scanning at ClusterTransactionService#scanProducerHeartBeat. Eventually, this producer will not be registered to brokers.
