论坛经常出现这个问题打不开，是怎么回事

Discuz! Database Error(2003) notconnect
PHP Debug

No.	File	Line	Code
1	forum.php	49	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, %s, %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()

刚才还好好的，过一阵子就出现这样了    还有经常更新缓存时也偶尔会出现这样

连不上数据库

这是你数据库不稳定导致的 不是啥bug 哦！
