Doesn't happen with me either.

Kernel IP routing table (andrew)

The network here is fairly complex, but straight forward. Two Linux
boxes acting as front ends for three other network segments. One box
(gateway) has two active NE2000 clones. The other box (andrew) has
three active SMC cards. The one with the NE2000's has a tunnel
configured. The same message comes up on both machines.
This is with kernel 1.99.8, gcc 2.7.2, and libc 5.2.18. I've tried
two different copies of mrouted, one was precompiled, the other I
compiled myself. The routing table is being maintained by gated
3.6alpha1 configured to just do RIP routing.

I've looked at the code. Unfortunately, it would take me about six
months just to understand the entire networking code architecture
before I'd be brave enough to touch anything.
