yyu1993 opened a new pull request #11939: URL: https://github.com/apache/kafka/pull/11939
When a log entry is appended to a Kafka topic using KafkaLog4jAppender, the producer.send operation may hit a deadlock if the producer network thread also tries to append a log at the same log level. This issue is triggered when idempotence is enabled for the KafkaLog4jAppender and the producer tries to acquire the TransactionManager lock. This is a temporary workaround to avoid deadlocks by disabling idempotence explicitly in KafkaLog4jAppender. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) -- This is an automated message from the Apache Git Service.
