Everything was working great for a few minutes. We issued a bunch of commands and all was good. We then went back awhile later and no output was being received. We are using a standard jabber.org account. We can see from the server log that messages from our IM client are reaching the server but we just don't get anything back. If we bounce the config (not rebooting or restarting hudson) we can see the hudson jabber disconnect/reconnect. We can then send 1 command and get a response. After that we get nothing back (the !status command for example).
