According to MySQL's help page on MEMORY engines...
当MySQL服务器停止或重新启动时，MEMORY表中的数据将丢失。
我正在亚马逊ec2 t1.micro实例上运行一个MEMORY表，直到大约一小时前，当我意识到我的所有MEMORY表都被擦除时，一切都相对正常。
我没有重置服务器，它仍然运行良好，虽然在我的日志中我意识到CPU负载变得非常高，因为我似乎有点太难推动服务器。
在崩溃前几分钟，CPU系统负载平均值为4.98, 3.32, 2.22 (1,5,15)。
单核微实例上的高CPU负载是否可能导致我的MySQL服务器停止＆＃34;停止＆＃34;从而丢弃所有内存表？
谢天谢地，我有一个备份...这次我没有推动服务器那么重新启动。
我已将我的MySQL error.log文件尾部复制到下面：

当我说CPU正在通过屋顶时，就发生了这种情况。我不确定这一切意味着什么，但我假设mysql服务器重置在这里。任何帮助将不胜感激。
