While testing Openfire 3.10.0 builds (same with RC) and running a bunch of clients on the background i have noticed that Jitsi is being kicked off by the server. My idle client policy is set to 30 seconds, so it happens every 30 seconds. If i set it to 5 seconds, it will disconnect and reconnect every 5 seconds. Tried 3.9.3 version and its the same.
Looks like Jitsi is not responding to xmpp ping correctly or Openfire is not sending or receiving ping packets correctly. Though other 6 different clients run ok. Looks more like a Jitsi issue.
Would report it to Jitsi also, but, they are using this archaic mailing lists system which i have no desire to use. So i will jsut post here as a placeholder if someone would report same issue or some information about a fix from Jitsi team.
