今天导入sql总是提示错误

ERROR 2013 (HY000): Lost connection to MySQL server during query
ERROR 2006 (HY000): MySQL server has gone away
No connection. Trying to reconnect...

网上试了很久，各种修改my.cnf，最后发现有人说是insert语句一次插入太多行造成的，解决办法就是每次insert一行

用mysqldump导出 加上参数--skip-extended-insert

不清楚是不是跟mysql版本有关，我的版本是
mysql Ver 14.14 Distrib 5.1.73, for redhat-linux-gnu (x86_64) using readline 5.1

总算是解决了问题，虽然还没闹明白为什么会有这种现象出现，大家有知道的还请告之一下，不胜感激
