          [OBS-4724] High CPU usage on Juniper EX4300 virtual chassis

          You realise we're not Juniper, right?

          The issue is with your switch. Ask Juniper. They're producing switches with broken SNMP stacks.

          trouble with (all) junos device - they have troubles with snmpwalk of whole ifTable oid. And this issue very related to firmware version.

          yep, you can make poller debug with this device_id (but this not make sense for issue, since you revert firmware version):

          ./poller.php -d -r -h 19

          Is that ok now?

          I had to rollback to Junos 14, if it doesn't mind.
