    Apache httpd with mod_cluster high memory consumption

      I've deployed my first infra-structure with JBoss and mod_cluster 1.1.3 and Apache 2.2.25 and I'm noticing that Apache memory consumption keeps getting bigger and bigger and bigger from a starting very low value to over 1.7GB...

       

      Is this normal?

       

      Apache only use is for mod_cluster, and I'm starting to believe that there is a memory leak somewhere..

          This is not normal, this would be a bug. 

           

          Do you have some exact instructions to reproduce? (ie a script ideally)

            Hi, sorry for the delay answering, but I'm a contractor, so one client, job done, next client....

             

            So far I notice that the memory consumption stabilizes at that level, no idea why is consuming such large values of memory.

             

            At least and so far the client hasn't complained...

             

            So no script nothing, just plain usage. Please note that the information between the client and the Jboss through the mod_cluster can have large files transmitted.

              Please note that the information between the client and the Jboss through the mod_cluster can have large files transmitted.

              In that case it may be using some buffers. What would be interesting is to isolate mod_cluster usage or maybe even try mod_jk and see whether the difference is really caused  by mod_cluster.

               

              There is no generic help or Jira I could just come up with.
