Our monitoring system is indicating transmit errors on the IPsec VTIs on our Vyatta Core routers when they are under high load. They only appear fairly occasionally, and don't appear to seriously impact performance (we're getting pretty close to 100 Mbps on a 100 Mbps link), but there seems to be very little information out there about what constitutes a transmit error on a VTI. I'm sure the information exists in the kernel sources, but having no kernel development experience, it could take me days or weeks to understand it enough to answer the question. Where can I find more information about this?
