Mysql不断重启(但我不知道为什么)

Question

我最近在日志中发现了以下错误

Oct 14 10:21:43 squire-labs kernel: [4186256.684193] init: mysql main process (16331) terminated with status 1

这经常发生(每分钟至少4次).我真的不确定导致这个问题的原因.Mysql在生产服务器上运行,具有足够的磁盘空间和内存.直到昨天我们从来没有遇到任何问题.

任何帮助都感激不尽.

事实证明，我在其中一个数据库中的一张表已损坏。事实证明这篇文章非常有用。

最后，我简单地创建了mysqldump数据库并将转储恢复到新数据库。这解决了问题。
