          Hello,

           

          You have to increase buffer sizes.

          On Linux systems, in /etc/sysctl.conf add those two lines :

           

          # Allow a 25MB UDP receive buffer for JGroups
          net.core.rmem_max = 26214400
          # Allow a 1MB UDP send buffer for JGroups
          net.core.wmem_max = 1048576
          

           

          Then run this command for the changes to take effect :

           

          sysctl -p
          

           

          Regards.
