IO broken with exception bind

Hi all,

We have troubles installing check_mk in one of our exchange servers. I am pasting the following log below

I have monitored the port 6556 (the default agent port) and nothing is listening there, Netstat nor TCPView can show usage on 6556, so it has to be something else. Is there any error code list for check_mk agents ?

Thanks

First you should try with a clean agent installation.
In your case there is minimum one plugin installed

Happens this also if you have no modified config installed?
