Hi Richard, This is normal, since we trigger an interrupt on every queue during our watchdog. So if the interface is up it should be triggering an interrupt on every queue every two seconds. This has (and will probably continue to be) necessary in order to pick up any straggler packets due to any (extremely rare, but expected to occur) missed interrupts that could happen when traffic is running. It also is extremely useful if you're doing irq affinitization and/or debugging interrupts. you can bring down the interfaces and they will stop interrupting.
