• 关于locate_resource表的错误

解决办法：检查mysql的 max_upload_packet值。默认max_upload_packet=1 改为max_upload_packet=16.

• PDOException: SQLSTATE[HY000]: General error: 2006 MySQL server has gone away: SELECT * FROM {menu_router} WHERE path IN (:ancestors_0, :ancestors_1, :ancestors_2) ORDER BY fit DESC LIMIT 0, 1; Array ( [:ancestors_0] => user/autocomplete [:ancestors_1] => user/% [:ancestors_2] => user ) in menu_get_item() (line 464 of D:\xampp\htdocs\moxingshe\includes\menu.inc).

这个问题可能可以通过修改服务器的配置解决。

1. 修改mysql的配置（my.ini）：

[mysqld]

...

max_allowed_packet=16M

这个值可以修改再大一点，如32M, 64M,128M.这个值用来限制server 接受的数据包的大小。

2. 尝试修改wait_timeout这个值，从30改为300.
