请教一下,下面的错误信息5分钟准时报一次,也郁闷不清楚是怎么回事。已经报了很长时间了。但目前数据库没有问题

觉得应该是有外部工具在定时监控你的数据库!

这个错误可以模拟出来,执行telnet  ip port,但是不要做任何操作,等待telnet自动退出,数据库就会报27001的错误。

This error usually occurs when the database server or the network is very busy or when too many clients are trying to connect to the database server at once.
增加连接数看看
