讨论IRIS log中 “Active server not defined, cannot redirect mirror connection” 是什么意思

从 IRIS log中找到了大量的以下内容：

05/05/22-01:05:11:375 (16166) 0 [Generic.Event] ECP: Mirror Connection request from 'SM25SDLMIIRROR:LOCALHOST.LOCALDOMAIN:IRIS' (10.xxx.xxx.27:33040)

05/05/22-01:05:11:376 (16166) 1 [Generic.Event] ECP: Active server not defined, cannot redirect mirror connection

这是什么意思?
