Hello, When restarting the firewall on routers running latest nightly, I frequently get the following warning:

If I compile an image with rtcache disabled (doing rmmod on the module triggers an oops), firewall restarts works fine. I tried to take a look at the code to check if I could spot anything obvious, but couldn't see anything.
