问题：
把MySQL从阿里云还原到本地之后，启动Tomcat7，从浏览器运行WEB系统报如下的错误：
### Error querying database.? Cause: java.sql.SQLException: Thread stack overrun:? 3480 bytes used of a 131072 byte stack, and 0 bytes needed.? Use ‘mysqld –thread_stack=#’ to specify a bigger stack.
### The error may exist in com/anche/systemService/page/page.xml
### The error may involve com.anche.systemService.page.dao.IDao_page.queryPageDataCount-Inline
### The error occurred while setting parameters
### SQL: {call? p_getDataCount (?,?)}

; uncategorized SQLException for SQL []; SQL state [HY000]; error code [1436]; Thread stack overrun:? 3480 bytes used of a 131072 byte stack, and 0 bytes needed.?

解决：
打开my.ini配置文件，修改
read_rnd_buffer_size = 256K
（原来是128K）
