Since deploying XMPP federation with gmail.com back in November, we experience intermittent service problems. As far as we know, and according to Google, the problem is experienced only by our domains - credit-suisse.com and credit-suisse.tv. Other domains running the same software and version we use have not experienced the issue.
The problem always manifests itself the following way. Outbound traffic to gmail.com from credit-suisse.com, presence and messages, always flows. Inbound traffic from gmail.com stops working for not apparent reason. Then, after 4 to 48 hours, it all starts working normally. I was able to capture the traffic while it was in the non-working state. According to our vendor Cisco/Jabber, what's happening is that gmail.com is trying to piggyback two streams on a single connection. The Cisco/Jabber server does not support this and cuts off the connection. What's puzzling to me is that Cisco/Jabber does not see this issue with their own federation with gmail.com and neither do any of their customers. Here's what the XMPP looks like when it fails (taken from a snoop session). Any insight would be greatly appreciated. <stream:stream xml ns='jabber:server' xml:lang='en' xmlns:stream='http://et herx.jabber.org/streams' to='gmail.com' from='credit-sui sse.tv' xmlns:db ='jabber:server:dialback' id='1D00006CAF' version='1.0'> <stream:stream id= "03D643FBF55AFC06" xmlns:stream= "http://etherx.jabber.org/streams";
