Error in log files

We are running openfire 3.9.3 with jitsi clients.

everything is working fine for more than a week now, except the fact that our users gets disconnected and instantly reconnected every 5-10 min. Even after checking “do not disconnect clients that are idle”.

However, going through the log files we see the following in our info.log

2014.10.03 10:31:06 org.jivesoftware.openfire.IQRouter - Packet sent to unreachable address

2014.10.03 10:31:06 org.jivesoftware.openfire.IQRouter - Packet sent to unreachable address

we also get the following in our warn.log

2014.10.03 10:36:23 org.jivesoftware.openfire.session.LocalOutgoingServerSession - Error trying to connect to remote server: server_name(DNS lookup: Server_name:5269): java.net.SocketTimeoutException: connect timed out

we enabled the debug.log and had the following
