抱歉，我的英语不流利。我是MySQL数据库的新手。我在 Windows Server 2022 Datacenter 上使用 MySQL 8.0.30。我有一个问题，MySQL 经常崩溃（MySQL 服务停止），并且总是带有相同的错误日志。我试图找到问题的根源，但没有解决。
有关信息，我在具有以下规格的同一设备上使用了 Grafana Web Server 和 MySQL： 处理器 Intel(R) Xeon(R) Silver 4208 CPU @ 2.10GHz 2.10 GHz 已安装 RAM 16.0 GB（15.6 GB 可用） 系统类型 64位操作系统，基于x64的处理器
请给我建议来解决这个问题。 先谢谢了
这是错误 MySQL 日志详细信息：

我尝试减少数据读写，然后增加客户端连接限制

每秒速率 = RPS
为您的 my.ini [mysqld] 部分考虑的建议，以避免意外关闭。
innodb_thread_concurrency=10 # from 33 for reasonable limit for your 16 available total threads innodb_redo_log_capacity=96M # from innodb_log_file_size name and 48M limit
**** 这是当前名称，而不是已弃用的每个错误日志的 innodb_log_file_size
innodb_buffer_pool_size=8G # from 124M for about 1/2 available RAM to reduce innodb_data_reads RPS of 31. read_rnd_buffer_size=32K from 256K to reduce handler_read_rnd_next RPS of 63,041 thread_cache_size=128 # from 10 to reduce threads_created RPS of ~ 5
请查看个人资料以获取联系信息。您有很多机会通过额外的全局变量更改来提高性能。
