we're experiencing these problem too, very sad!
we have a lot of routers on our pops and some of them when something happens to ospf like a neighbor down, or we just change some router ospf priority, some routers crashs ( 100% cpu) and all routes goes away and we have to do a system reboot. some others doesnt crash but generates an autosuppout files. and our core routers with about 30 bgp sessions restarts all its bgp sessions what is a pain!
The ones that crashs and we have to reboot are running 4.13 and the ones ( core routers) that looses all bgp peers like the the bgp proccess and ospf proccess sound like tied togheter and restarts it self ( better than 100% cpu and crash like 4.13) are running 5rc2.
Please MK stuff take care of routing proccess carefully. my boss is going to kill me as we allways supported mikrotik , but we cant live with these routing bugs thats take all our network down from seconds ( on rc routing proccess auto reset) and minutes on 4.13 that we have to manualy reboot the routers.!!
Wired routing is still buggy, Did you suffer from the OSPF crash's that take down routing up untill 4.13?
MT's has its place but that place is becoming less and less about wireless and more about it's core routing and/or wired systems, I'm also in the camp of needing a more complete IPv6 feature set. I hope you have jumped up and down at support as they have stated v6 isn't getting enough requests to justify work on it
