19:15:41Logical Log 149723 - Backup Completed 如果重启数据库是否有用？？ 试试增加数据库的连接数。。 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telnetip 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 谢谢分享啊。
