Hi, this shouldn't happen if ifplugd is started using the hotplug scripts, so if the interface is in HOTPLUG_INTERFACES in /etc/default/ifplugd. Is that what you are doing?
You can also use the -M option for ifplugd. I can reproduce the bug without that option (I see spikes in the CPU usage), but not with the -M option. Greetings, Oliver
