    Wildfly 8.2 and Java web start, wierd problem

    Maycon Oliveira Newbie

      Hi there.

       

      I´m facing some strange problem with Wildfly 8.2 and java web start. I have this enviroment running on a VPS server with not so good latency numbers.

       

      When i start the jnlp file, the apache server that is in front of wilfly crashes with 503 erros. 

       

      At the begging I thought it was apache server problem, but on the apache logs, appear that wildfly stopped to answer the apache calls e then the apache returned 503.

       

      Digging on the net i added this parameters on standalone.xml:

       

      <worker name="default" io-threads="100" task-max-threads="100"/>

       

      This appeared to solve the problem, but on the 3º try, the problem happend again (before the parameters the problem happen on first attempt).

       

      Wildfly logs are clean, and this only happen with java web start, the web app runs ok

       

      Any clues? 

       

      Thanks!

            DUmping the requests and the responses, seems that apache is rejecting 304 responses from wildfly and transforming then in 503 for the client.   Can be it?
