This is a reporting problem, and probably due to the schedule() call and associated task state in the ips-monitor thread. I thought setting the task state to interruptible would prevent this, but it seems like it's not enough for the deferrable on-stack timers?
At any rate, it's not actually causing increased CPU usage, so you can safely ignore it until we have a fix.
