    sticky session fails

      Dear mod_cluster forum,

       

      we are using mod_cluster 1.2.6 on a linux based cluster. We have several applications hostet on JBoss 7.1.3 on 3 different servers. One server is named sl70161-243 and one other sl70162-244. One of our applications (abc) uses sticky session.

       

      Sticky sessions are working in general but for some reason sometimes requests are forwarded to a wrong JBoss. We recorded some debug logging. Mayby someone can give me a hint what the problem might be.

       

      Here is the log:

          Hmm, could you reproduce it with the latest 1.2.x branch, i.e. 1.2.10?

            Hi Michal,

             

            it would be very difficult to make a try with 1.2.10. This problem can onty be reproduced on a customers system which is due to the processes of the hosting componany very difficult to change.

             

            I was hoping that the logfile shows something that I am not able to identify as problem and what can be the key for further analysis.

             

            Thx

              Hi Michal,

               

              after some code study (1.2.6) it seems to me like the stickieness gets lost in the method "internal_find_best_byrequests".  "mycandidate" points to the wrong server. I don't understand the algorithm in detail but it looks like the list of works is updated by calling "update_workers_node" and than the proper worker is looked for in the while/for loops.

               

              What I don't understand by now is how "sticky session" and "sticky session force" is considered for the determination on "mycandidate".

               

              Please can you give me a hint about sticky sessions and mycandidate.

               

              UPDATE: It looks to me that the problem occurs earlier. "find_best_byrequests" should never be called wheen sticky session is used and a proper route is given in jsessionid, right? If that right I think the problem occurs in "find_route_worker" where no worker can be found for the given route. How can I find out if a node is temporarily unavailiable? 

               

              Thx

              Alex

                BTW do you have session replication set up? Just wondering, because in that case a failover to another server should not lose the session creating a new one on another server. Are you using sticky-session-force?

                  Hi Radoslav,

                   

                  we don't use session replication because of the framework we use for older parts of our application that does not support session replication.

                   

                  Yes, we use sticky-session-force.

                   

                  Thx
