Constant disconnects due to channels going stale f

Question

Ever since the latest release a few days ago, our users are constantly being disconnected due to channel tokens going stale with minutes of being created. Our tokens are set to last for 5 hours, but we're lucky if they last for 5-10 minutes and we cannot even reconnect with a new channel token when the channel closes until the user refreshes.

A Javascript error triggers the beginning of it. It looks like this:

NetworkError: 400 Unknown SID - http://89.talkgadget.google.com/talkgadget/dch/bind?VER=8&clid=C9C2EFC06C7C5163&gsessionid&prop=data&token=AHRlWrrWl611ZMMDw8Apgi5vdYuS9UslofxEiJI47-2n4rkPgmuu1z0AN-UNQcyNEvhck-AYAMSLPru8Aumooz62hYNNbLTbi1a3lTSAzGEyj6TsXZirJYE&RID=rpc&SID=BEBDEFDA92C6A9F7&CI=0&AID=54&TYPE=xmlhttp&zx=gsjg8mb1i987&t=1

Then, in Firefox Firebug, the console gets spammed infinitely with

channel name mismatch; message ignored

Until a refresh occurs.

Our site is a real-time interactive site with chat. Our users are sending us emails upset that they keep getting disconnected. They're leaving the site. This is costing us not only goodwill with our user base, but also money and we are powerless to do anything because the bug is with Google App Engine.

Please fix this or rollback to the previous build immediately until you figure this out. The latest build is broken.

I haven't been able to reproduce this but I'm still looking at it. In the meantime: if you explicitly call socket.close() after receiving the error, can you then create a new Channel object and reconnect? If that doesn't work, you could even try manually removing the element with id "wcs-iframe" itself from the DOM. You should be able to use the original token when doing this instead of fetching a new token.
