Port address of publisher server changing everytime while distributing as per logs

[adcgermany]

Hi All,

As per qlik, qlikview will use only specific ports like 4747,4720,etc . But in our environment , we can see the port number of publisher is changing everytime we distribute an application . Below 63194 is used as publisher port. Is this expected ?

Actually we are facing one intermittent distribution failure issue and that's when we checked this

900 Debug QvSocket: Read error (end of file) on [TCP socket 25.0.8.14:4747 <-> 25.0.8.16:63194]

Socket communications using TCP/IP work like this:

• you have a listener that listens on a well-defined port for connections (usually, this listener does this all the time because this service can't know beforehand when requests for a session will arrive.) Thats the documented port which is 4720 for the QDS (see QMC if you have a different configuration) or 4747 to talk to the QVS using the QVP protocol.
• you have a client that wants to talk to the service that is listening on this well-defined port. This client can use any unused port between 1024 and 65535 to start talking. In your example the client who is initiating the connection is using port 63194. In most cases, ports are randomised so you won't get the same port twice.

I don't immediately see any indicators of problems in your log file snippet.

Hi Peter ,

Thanks for the response .

Hi,

It appears that the Distribution service can't connect to the QVS server to upload the file.

Connecting to QlikView Server. Address=abtaws-qvsrqa1:4747

It could be that the QVS is offline, DNS can't resolve the name abtaws-qvsrqa1 or port 4747 is blocked
