I have trouble with 6.* version software. I have x86 server with software - 5.25 and all works fine. On this router run - ospf, static routing, pppoe for the clients, bgp mpls vpn, firewall filter and mangle. I try to upgrade to version 6.*. And router work unstable. He could work about 30-40 minutes fine, but then all ospf neighbours change state to down, one of the proccessor cores have 100% load, helps only restart. The same situation is with the CCR1016-12G.
