总是间断出现Discuz! Database Error，刷新又好了。还有通信连不上，其他正常。

Discuz! Database Error(2003) notconnect
PHP Debug

No.	File	Line	Code
1	portal.php	18	discuz_application->init()
2	source/class/discuz/discuz_application.php	65	discuz_application->_init_db()
3	source/class/discuz/discuz_application.php	370	discuz_database::init(%s, Array)
4	source/class/discuz/discuz_database.php	23	db_driver_mysql->connect()
5	source/class/db/db_driver_mysql.php	74	db_driver_mysql->_dbconnect(%s, %s, %d, %s, %s, %s)
6	source/class/db/db_driver_mysql.php	87	db_driver_mysql->halt(%s, %d)
7	source/class/db/db_driver_mysql.php	218	break()

求指教！

该问题有可能是数据库不稳定导致的短暂中断连接。
