    Hi Manjunatha, could you please let me know what the root cause was and how you fixed this issue (as we see the same error messages)?

     

    thank you, stefan

    Hello,

     

    Can someone tell us how to resolve this problem?.

    Hi Henry:

    Without the logs showing the full exception, we will be unable to tell. Please open a case with the appropriate logs if seeking a solution.

     

    Thanks

    Without all of the error details, I would suspect that you may need to configure the concurrency pooling in IntroscopeEnterpriseManager.properties.

     

    Has this been done?

     

    transport.outgoingMessageQueueSize=6000

    transport.override.isengard.high.concurrency.pool.min.size=10

    transport.override.isengard.high.concurrency.pool.max.size=10

    I clarify that telnet works over ip address ***.5.0.*** and the port 5000. I have access to the WebView and Team Center only for two minutes, after that the linux console show me this:


    Problem while starting WebView server. Please check .../logs/IntroscopeWebViewConsle.log for details.

    Is it configure over https? http port defined in the webview properties file or of the https port defined in the jetty config file.

    Make sure its configured correctly.

    Were you able to solve this issue?

     

    Thanks

    One more thing, this problem occurs when you start the WebView by the script WVCtrl.sh, via nohup this same problem does not occur.
