動物園管理員會話持續到期...沒有心跳？

我們正在使用卡夫卡高級消費者，並且我們能夠成功地使用消息，但動物園管理員連接仍然過期並重新建立。動物園管理員會話持續到期...沒有心跳？

我想知道爲什麼沒有心跳，保持連接活着：

我剛剛在我的Mac上開始出現類似的問題（單個節點Kafka/zookeeper開發集羣）。你在Mac上運行嗎？ –

它對我來說是Linux ... nd單節點集羣 – nikel

我的問題在IntelliJ IDE中以調試模式運行而加劇。從命令行運行我們的Scala應用程序更加穩定 –

通常的ZooKeeper會話超時由「軟故障」，這是最常見的垃圾收集暫停造成的。打開GC日誌記錄並查看連接超時時是否發生長期GC。另外，請閱讀JVM tuning in Kafka。
