Kafka出现报错Too Many Open File

We apologize that the translated content is not provided to this page.

起因

Kafka无故宕机，查看log发现报错Too Many Open File

处理

  1. 检查ulimit -a，发现open file大小正常，接近内核最大允许/proc/sys/fs/nr_open的1048576
  2. 修改kafka参数num.replica.fetchers由10改为60，观察效果

笔记

ulimit

  • nr_open

  • num.replica.fetchers

参考

linux下设置最大文件打开数nofile及nr_open、file-max说明
