Hi,

I have some doubt regarding communication channel monitoring.. one of my scenario's communication channel has some problem. I have seen some log when i was monitoring the channel,

Please look into the below information for the same.

I found this error.. " Channel has internal error" and in the Administration information tab

Exception: Channel with Status Unknown or Not Registered

What does Channel with Status Unknown or Not Registered exactly means ... ?
