mysql偶尔会重启

Question

在晚上，我们的mysql服务器偶尔会重启(innodb引擎)，在日志中我看到了以下内容：

150921  1:58:44  InnoDB: Page checksum 2064838754 (32bit_calc:  866699801), prior-to-4.0.14-form checksum 400856538

有没有可能透露发生了什么，以及我们应该做些什么来进一步避免这种行为？

我想那张桌子坏了。你可以使用备份修复命令: First MySQL！https://dev.mysql.com/doc/refman/5.0/en/rebuilding-tables.html
