I've recently been getting disconnected from video chats with a friend after 10-20 minutes. I have Messages 7.0.1 and my friend uses iChat. We've both set our bandwidth limits to 500 kbps. Here's a recent error log from Connection Doctor:

 

2012-11-17 15:58:38 +0000: No data has been received for the last 10 seconds.

Audio channel info: local machine using 10.0.1.8:16402, expecting remote machine to send to 69.253.7.132:57785

Video channel info: local machine using 10.0.1.8:16402, expecting remote machine to send to 69.253.7.132:57785

 

Could you please help me troubleshoot the problem?

    HI,

     

    This error occurs when the connection is cut by something outside or iChat/Messages control.

     

    This could be a dropped WiFi signal between one of the computers and the router at that end.

    It could be a interruption with the services from the Internet Provider.

     

    The 500kbps limit can help if the Internet Connection varies a great deal in speed.

    It can also help with those ISPs that slow the connection thinking Peer-to-Peer File sharing is going on.

    A video chat is essentially Peer-to-Peer (when not using the AIM option to relay through their servers) and it seems most ISPs don't check further. The 500kbops seems to "be under the radar"  in these cases.

     

    If the issue is happening regularly  and appears to be around 15 minutes  (Depending when you start the chat) it would seem that something regular is happening on the network  (The LAN at one end) that is cutting the amount of Bandwidth that the Video chat can access.

     

    In some cases the issue can be caused by a slow(er) processor getting caught up doing something at one end.

    iChat was designed to allow other apps to access the processor first.

    This couples with a heavy download of new Mail or the constant refreshing of a data intensive web page can be the cause.

     

    On this front one cause can be Time Machine trying to start a Backup

    Hi,

     

    If you and your Buddy are getting the same message  then the time data may provide a clue.

     

    Your error log was timed at 15.58 and 38 seconds.

     

    The end that got the message first is like to be the OK end.

     

    However it is not always that clear cut.

    Some people get this message before seeing and Video or hearing their Buddy.

    In these cases it means they were connected but almost immediately something broke the connection.

    In these cases the person with the first messages should look to their router and "protection" features.

     

    Namely they should turn Off DoS (Denial of Service)  or SPI (Stateful Packet Inspection)

    The first is Threshold Based that iChat video can exceed.  The second relies on the router's processor which cannot keep up in Video chats. (At a certain point it gives up and cuts the one por the data is on.)
