The split route itself may not be the culprit but I can safely say that without using the split route, my system is perfectly stable. I have set up the split route according to http://www.tldp.org/HOWTO/Adv-Routing-HOWTO/lartc.rpdb.multiple-links.html I could use the multipath routing to access the internet ( NAT ). I could also do multipath in-bound port forwarding using netfilter CONNMARK etc etc. It is also not the fault of CONNMARK, because without using it I experience the same problem. The problem I have is that I get frequent connection lost ( like very 20 minutes or so for my connections ) and eventually I will get a kernel panic. Short connectionless session such as web surfing won't see anything unusual. I suspect the iptables interaction with multiple path routing is giving me this problem. Anyone experience the same thing before ?
