Eu tinha um problema parecido com esse num provedor que eu trabalhava
e era relativo a este changelog
What's new in 4.3:

*) kvm - vnc support, booting from cdrom image
*) API - fixed possible crash when running concurrent commands;
*) console - fixed logging commands: 'warning', 'error' and 'debug' were
    all using 'info' topic;
*) bgp - added routing-table configuration option for instances;
*) bgp - added 'as-override' and 'passive' configuration options for peers;
*) bgp - added support for Site of Origin extended communities;

*) bgp - fixed some network issues;

Logo que eu atualizei para a versão 5.0beta a coisa se resolveu.
Apartir daí não fiz mais BGP com mikrotik, quem sabe realmente seja um
novo bug que eu desconheço.
Tentem fazer o downgrade pra testar.
