    Solarwinds stuck polling route table Juniper MX router

    jajao555

      We have two Juniper MX routers that are still getting bulk request from Orion even though we've unassigned all nodes in the Routing poller. We've also tried checking it in List Resources then unchecking it again but didn't help. We haven't tried readding the nodes yet as we'd like to save the stats if possible. We have dozens of other MXs and no others are having the same issue. Any reason Orion would continue polling these two routers? Both have a standard snmp config used on all the other routers and there doesn't seem to any other issues with them.

       

      Here's what we see in a traceoptions. We see the request come in from Orion.

      Then we see the router respond and start sending entries from its entire table causing constant CPU spikes.
