    Nprinting 17 verify connection issue

    Oreste Ciotoli

      Hello,

       

      i'm not able to verify anymore the connections in Nprinting:

       

      connection issue 1.PNG

       

      Looking from the webengine.log:

       

      "Uncaught exception serving the request http://dwh-ix-001:4996/npe/connections/verify Already closed: The AMQP operation was interrupted: AMQP close-reason, initiated by Library, code=541, text="Unexpected Exception", classId=0, methodId=0, cause=System.IO.IOException: Unable to read data from the transport connection: An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full." ...


      This connection worked properly 2 weeks ago, but few days ago i've tried again with this result. Does anyone had the same issue?

          Ciao Oreste,

           

          Please check that all Qlik NPrinting Windows services are up and running. In case try to stop and restart them.

           

          It seems a communication issue.

           

           

          Best Regards,

          Ruggero

            Greetings! As Ruggero suggested, kindly try to stop all the Qlik NPrinting services and reboot the server. If the issue still persists, Please check if any service stop command are timed out. If you are running batch file for start/stop NP services.

             

            Thank You

                If after rebooting the issue is still present, please check or share here the log files.

                Hello guys, thanks for the support. Restarting the server was enough to solve the issue!
