Hm... this is quite interesting... Does it often happens? I'm aware only of 2 places where routing can be removed: 1. hotplug, which I mentioned already. maybe some other "clever" daemon running on your system? RIP/OCFS? 2. OVZ crontab sript which should delete dead routes. can you check this one as well? All I can suggest for debugging is to: 1. replace ip and route commands with a wrapper which logs the exact commands and when/who called them. 2. add similar debug to kernel. BTW... does your host system uses DHCP or static IP assigned?
