MySQL服务意外停止

　　先说一下，发现MySQL服务停了，启动就又好了，但是好奇服务意外停止的原因，所以看了一下MySQL的错误日志。

但是到底是哪个错误导致MySQL服务意外终止，还没有定论，故有了此篇文章，还望知道原因的大侠能告知~

环境：

　　OS: windows server 2012 R2

　　MYSQL: MySQL5.6

错误日志提示（部分）xx是被我替换后的:

感觉关键信息有以下几点：

1.The table 'xxx' is full

2.Encountered a problem with file xxx.ibd

3.Disk is full

4.trying to access page number 4294967289 in space 5481

然后网上查资料呗~

结论：

结论1：bug说：

　　即“trying to access page number ”是mysql的一个bug 链接：链接

结论2：磁盘满了（可能性较大）

　　依据：Mysql:The table‘xxxx’is full 、Disk is full和“Encountered a problem with file xxx.ibd”（xxx是表名）

·　　我们这个服务器在7-16号确实发生了数据库所在磁盘磁盘空间被占满，剩余空间为0的情况。

　　可是上次磁盘满了，数据库并没有挂啊，只是apache服务也没有挂。只不过apache写服务器的访问日志时出错，我删除了一些磁盘上不用的文件，并重启apache就好了。

　　而且table is full的信息，在16号就出现了，但是当时mysql服务并没有挂啊。

　　难带是因为table is full出现次数过多，导致数据库文件损坏（猜测，网上没有查到相关资料佐证），进而导致MySQL服务挂掉（也是猜测，网上没有查到相关资料佐证）？
