Description

After enabling Juniper Resiliency Interface on an MX10k8, both the installed FPC's in slot 0 and slot 8 enter a cyclic reboot. Sample configuration as following.

chassis {

  fpc 0 {

    pfe 0 {

      exception-reporting {

        category firewall {

          inline-monitoring-instance JRI_MON;

        }

        category forwarding-state {

          inline-monitoring-instance JRI_MON;

        }

        category layer2 {

          inline-monitoring-instance JRI_MON;

        }

        category layer3 {

          inline-monitoring-instance JRI_MON;

        }

        category packet-errors {

          inline-monitoring-instance JRI_MON;

        }

      }

    }

}

}

Note that the same problem can be seen with MPC2E-NG, MPC5E. The MPC10E and latest MPC type are stable.

Symptoms

MPC keeps coredump once enabled "exception-reporting category packet-errors".

Solution

This problem is with "exception-reporting category packet-errors" configure. Problem will be seen in releases that have PR1684382 fix.
