couldn't setup local SOCKS5 proxy on port 7777: Address already in use

I found NodeID test1 in mysql, but I can't found nodeitem..

I can't push my item below because of error message. Is anything wrong?

<iq id="XIv9Y-6" to="pubsub.desktop" type="set">

     <pubsub xmlns="http://jabber.org/protocol/pubsub">

          <publish node='test1'>

               <item id='test's service list'>

                    <serviceName>

                         <service>test.test</service>

                         <ip>115.145.179.149</ip>
