Looks like it is leaking the 'rt->rt_refcnt' and as result it =
crashes/panic at RTFREE() on the end of route_output().
I don't have access to this live system to dig further (i.e. reduce the =
test case).

Hello,
I've found another (easy) way to reproduce the problem with two scripts:
routes-add.sh and routes-remove.sh.
First run routes-add.sh for a while; then execute routes-remove.sh.
Cancel with CTRL+C and execute routes-remove.sh again.
Scripts:
========
# cat routes-add.sh
#!/usr/local/bin/bash
for a in {11..16}; do
for b in {1..255}; do
for c in {1..255}; do
echo -n Adding route $a.$b.$c.0/24...
route -q delete -net $a.$b.$c.0/24
echo OK.
done
done
done
# cat routes-remove.sh
#!/usr/local/bin/bash
for a in {11..16}; do
for b in {1..255}; do
for c in {1..255}; do
echo -n Removing route $a.$b.$c.0/24...
route -q delete -net $a.$b.$c.0/24
echo OK.
done
done
done

Again, removing RADIX_MPATH from kernel, it's working fine.

Hi Eduardo,
I've found another problem while trying something like you'd proposed, but it can be easily reproduced by just trying to remove a network route that is not in the table (probably what your script does when you press ctrl+c and restart it).
The problem i've found produces the following backtrace:

Are you sure that your scripts produce the backtrace you'd posted ? I cannot reproduce that here...
Well, about the problem i've found ("radix node disappeared") when removing a nonexistent route (route delete x.y.w.z/24 - where x.y.w.z/24 is _not_ in the route table), it was related to the code that check for a gateway when there are multiple gateways for a route, which clearly was not the case.
After some thought i've crafted the following patch which fix the "radix node disappeared" problem (for me obviously...), can you try your scripts with this patch ? Not sure yet if this is related to the first problem you'd reported.
Thanks,
Luiz

I'm using Quagga 0.99.17 peering with bgpsimple tool in another machine. Bgpsimple injects full-routing table in this bgp session. When the bgpsimple terminates the injection (or when I cancel by pressing CTRL+C), an kernel panic occurs in the router.
