Hi Paolo, thanks for your reply!

I've since compiled 0.14.3 from source and it works perfectly :) As for Quagga, we are running 0.99.15. I can't say that i see a clear pattern, but i was able to reproduce rather consistently by restarting nfacctd and flapping the BGP session from the router. The amount of UPDATEs we received before seeing the malformed packet varied. After the initial bad packet from UPDATEs we would see the usual BGP OPEN and KEEPALIVE before getting the error again causing the BGP session to reset and starting over again. If you are still interested, even though updating to a more recent version solved it, i'd love to help out with any information i can provide. Thanks again!
