Re: AvConvMsg_MC error message

The two groups of errors (MIU and Conversation) are not related. The Conversation errors showed up because there is esentially there has been an infinite loop programmed in Unity (Call Handler A goes to Call Handler B, and Call Handler B goes right back to Call Handler A--or something like that).

The MIU error could very well cause a Unity port to burn, but it should not cause all Unity ports to burn. When it is mentioned that "Unity" stops working, does that mean that Unity does not answer, Unity answers to fail safe, or calls directed to Unity go no-answer?

Whatever the case, you should probably contact TAC about this.
