> The producer is stuck during the close. It keeps retrying to abort the transaction but it never succeeds.

> ch-transaction-id-f60SGdyRQGGFjdgg3vUgKg, transactionalId=transaction-bench-transaction-id-f60SGdyRQGGFjdgg3vUgKg] Error in kafka producer I/O thread while aborting transaction:

> With the additional log, I found the root cause. If the producer is in a bad transaction state(in my case, the TransactionManager.pendingTransition was set to commitTransaction and did not get cleaned), then the producer calls close and tries to abort the existing transaction, the producer will get stuck in the transaction abortion. It is related to the fix [https://github.com/apache/kafka/pull/13591].
