当 MySQL 服务器停止或重新启动时，MEMORY 表中的数据会丢失。
我在 Amazon ec2 t1.micro 实例上运行 MEMORY 表，直到大约一个小时前，当我意识到我的所有 MEMORY 表都已被擦除时，一切都相对正常。
我没有重置服务器，它仍然运行良好，尽管在我的日志中我意识到 CPU 负载变得相当高，因为我似乎有点太用力地推动服务器。
4.98, 3.32, 2.22 (1,5,15)崩溃前几分钟，CPU 系统负载平均值正在读取。
单核微实例上的高 CPU 负载是否有可能导致我的 MySQL 服务器“停止”并因此删除所有内存表？
谢天谢地，我有一个备份......这次我将重新启动，而不是如此努力地推动服务器。
我在下面复制了我的 MySQL error.log 文件尾端：

这发生在我说 CPU 正在冲破屋顶的时候。我还不确定这一切意味着什么，但我假设这里的 mysql 服务器已重置。任何帮助，将不胜感激。
