Ошибка запуска сервера jpos Q2: java.net.UnknownHostException

Я развернул автономный сервер Q2 на машине с Linux (centos). При запуске сервера Q2 я получаю UnknownHostException. Я не могу понять, на какой хост ссылается сервер Q2. Я использую конфигурацию на основе channel_adapter, server_config, qserver_mux и txnmgr_config xml в папке развертывания. То же самое работало, пока я не перезапустил службу. Найдите выдержку из q2.log.
