我试图启动Kafka服务，但它给出了以下错误。
● kafka.service - Apache Kafka server (broker) Loaded: loaded (/etc/systemd/system/kafka.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Wed 2021-11-17 06:16:12 UTC; 46min ago

我们试图通过增加ulimit来快速修复，但我们每天都面临这个问题。需要永久的解决方案

要调试此问题，请尝试在Kafka代理进程上发出
lsof，以获取Kafka代理已打开的文件列表。主题分区是文件夹。检查您的
segment.ms或segment.bytes，看看Kafka是否设置为经常滚动新段，这最终会创建大量文件。您可能还需要考虑添加新的代理 *（如果需要 *）。
请确保您使用的是Kafka 2.1.1+。查看此票https://issues.apache.org/jira/browse/KAFKA-7697
