I have deployed standalone Q2 server in linux (centos) machine. When starting Q2 server i am getting UnknownHostException. I am unable to figure out which host the Q2 server is referring. I am using channel_adapter, server_config, qserver_mux and txnmgr_config xml based configuration in deploy folder. The same was working till i restarted the service. Please find the extract of q2.log.
