MySQL ...开始崩溃恢复

Question

我一直在寻找解决这个问题的方法。我的 MySql 给出以下读数:

121231 20:41:05 [Note] Plugin 'FEDERATED' is disabled.
121231 20:41:05 InnoDB: The InnoDB memory heap is disabled
121231 20:41:05 InnoDB: Mutexes and rw_locks use Windows interlocked functions

121231 20:41:05 InnoDB: Initializing buffer pool, size = 512.0M
121231 20:41:05 InnoDB: Completed initialization of buffer pool
121231 20:41:05 InnoDB: highest supported file format is Barracuda.
InnoDB: The log sequence number in ibdata files does not match
InnoDB: the log sequence number in the ib_logfiles!
121231 20:41:05  InnoDB: Database was not shut down normally!

121231 20:41:07 [Note] Server hostname (bind-address): '0.0.0.0'; port: 3306
121231 20:41:07 [Note]   - '0.0.0.0' resolves to '0.0.0.0';
121231 20:41:07 [Note] Server socket created on IP: '0.0.0.0'.

121231 20:41:09 [Note] c:\xampp\mysql\bin\mysqld.exe: ready for connections.
Version: '5.5.27'  socket: ''  port: 3306  MySQL Community Server (GPL)

每次启动时。我尝试过删除文件、删除数据库、运行 Magento 的修复数据库工具、使用新数据库重新开始，但无论怎样我都会收到此错误。

这让我感到不舒服，因为我不确定某些东西是否会损坏或已经损坏。我使用的是 Windows Vista 和 Xampp，但我也使用了 nginX，显示了相同的内容。

我刚刚重新创建了一个全新的数据库，现在关闭后(我有时必须这样做)，错误再次出现!这是正常现象还是有什么问题？

谢谢

从日志中可以看到InnoDB开始崩溃恢复:

InnoDB: Starting crash recovery.

原因是 MySQL 关闭不干净。为什么？可能是 MySQL 退出时间太长，操作系统杀死了该进程(如果您重新启动服务器)。或者 MySQL 由于错误而崩溃。
