During one of our test, we found that all the produce/consumer request to one of our kafka broker got timeout, and the server of this kafka broker holds more than 200K `CLOSE_WAIT` network connections and it grows continously. After research the jstack output of Kafka broker, we found a *{color:red}DeadLock{color}* and a Lock(0x00000005c109dd50) which waited by many thread and no one hold it. You can see the attached file for more detail.
