I think that "$classid" is outside its allowable range when that line
executes, although it is also possible that the RTNETLINK message is due
to an erroneous value in "$dev", "$ip" or "$table".
Your script can be modified to display the line with the substitutions
and to exit when executing causes an error. What I envision is that
you'll watch 2000+ lines of good stuff scroll by and that the final line
will be your Bad Boy. And the last few lines are what we all are
holding our breath to see <grin>.

I still don't think it is how many. I am certain that some value is
just not in the expected range.

I think the line above should count down from 65535, not up.

And here is where you need to display the Action line.
Plus add an error trap to exit when it fails.
Sorry, that's all I have time for now.
