    503 for all 4 webservers

    M Muthukumaran Newbie

      Hi,

       

      Versions:

                - 4 webservers running Apache 2.2.15

                - 3 app servers running Jboss EAP 5.1.0

                

      We have a very strange issue that happens in our production servers. Suddenly one fine day we recieve 503,this issue happens at random intervals.

       

      Only way we had fixed this is to restart the apache servers and issue resloves, this happened multiple times in the past months.

       

      When this issue happened I verified the following things

      - I was able to access our application going directly to jboss 8080 port

      - There was very minimal load on the Jboss servers

       

      During this time frame I see these error in the apache server logs. Please help me with any suggestions.
