我有一些问题与Kafka和zookeeper，我有3x Kafka经纪人和3x zookeepers.我得到了几个Kafka问题从我的容器，有些有这样的：

time="2023-12-26T09:46:00Z" level=error msg="Failed to produce message {low_priority[-1]@0 [123 34 99 111 109 112 111 ......] 0001-01-01 00:00:00 +0000 UTC NotAvailable <nil> []} with producer &{rdkafka#producer-1 x}"

字符串
其他人有这样的：

future: <Future finished exception=LeaderNotAvailableError()>
kafka.errors.LeaderNotAvailableError: [Error 5] LeaderNotAvailableError

查看Kafka日志，似乎没有什么不寻常的。Zookeeper有这些日志：

[2023-12-25 13:23:14,197] WARN Close of session 0x0 (org.apache.zookeeper.server.NIOServerCnxn)

我不明白这个问题。也许是zookeeper内存不足？类似的问题？任何提示都将不胜感激。谢谢
