首先是discuz 连接不到数据库，查看系统日志出现警告：Changed limits: max_open_files: 2048 max_connections: 2038 table_cache: 64 的问题，经过一番调试这个问题没有了，但是有时还是连接不上，用netstat -a查看：
TCP web:4299 web:3306 TIME_WAIT
TCP web:4300 web:3306 TIME_WAIT
TCP web:4301 web:3306 TIME_WAIT
TCP web:4302 web:3306 TIME_WAIT
TCP web:4303 web:3306 TIME_WAIT
TCP web:4304 web:3306 TIME_WAIT
TCP web:4306 web:3306 TIME_WAIT
TCP web:4308 web:3306 TIME_WAIT
TCP web:4309 web:3306 TIME_WAIT
TCP web:4310 web:3306 TIME_WAIT
TCP web:4311 web:3306 TIME_WAIT
TCP web:4312 web:3306 TIME_WAIT
TCP web:4313 web:3306 TIME_WAIT
TCP web:4314 web:3306 TIME_WAIT
TCP web:4315 web:3306 TIME_WAIT
请问这是什么问题，该如何解决？

长连接没有释放的原因，设置两个参数：
interactive_timeout =200
wait_timeout=200
