操作系统升级后，Kafka Brokers连续自动重启

Question

我有一个基于Kafka的3节点3 Zookeeper。 我使用的版本是0.11.xx

最近，我们在两个生产集群的基础VM上进行了OS升级。

升级后，其中一个群集运行良好，但是另一个群集运行良好，我看到Kafka代理会自动重新启动。

这种自动行为每分钟发生至少15-20次。

我会怀疑它是否是配置问题，因为在另一个群集上实现了相同的更改（配置与有问题的群集相同），并且运行良好。

尽管与其他群集相比，CPU负载略有增加，但CPU和内存使用似乎正常，但仍处于可控范围内

为什么会发生这种情况的任何具体原因？

我粘贴了错误日志，这些消息似乎一次又一次地出现
