    Fuse ESB Cluster generate "too many files opened"

    Franck Sandreau Newbie

      Dear all,

      We have a very complex problem using FUSE ESB 6.3 redhat-630254. For some reasons, on each cluster's node, the number of file descriptor used exceed the limit (more than 65000).

      Our architecture is based on 5 nodes with the bundle service deployed on each one (using Fabric profile).

      We are using :

      camel vesion 2.17.0.redhat-630187

      camel-netty4-http version 2.17.0.redhat-630187

       

      Below the exception :
