Doing some research I can see a some people had the same problem: like this: http://lists.freebsd.org/pipermail/freebsd-current/2011-August/026794.html unfortunatelly the patch is not available anymore. But this is not the worst part. The most curious thing is: I have 2 identical servers (DELL R410), with the same set of network interfaces (2x bce and 2x igb). I am using the same version of O.S (Freebsd 8.3-STABLE) on both of them and the kernel was built using the same config. The quagga (quagga-re) are exactly the same as well, and they are neighbors on my network by the way. Everything works great in one of them, but the kernel crashes in the other a couple minutes after get quagga running. The main difference between them is, the server who crashes, acts is a border router (EBGP, IBGP and OSPF), and the router working fine is a distribution router (OSPF only). I "GUESS" I would have the same crashes in the working router if I start an ibgp neighboring (and receive > 420K prefixes.) The crashes go away, when I remove RADIX_MPATH. Any thoughs are very welcome.
