x86 v5.12 multiple bgp issues

RouterOS General
1

Note: Our systems have been upgrade from 5.8 to 5.11. We hit the now well known bugs, we downgraded to 5.8 and it wasn’t as stable as before. It just kept flapping the sessions with our peers. We upgraded to 5.12 and the lack of stability continues.

X86 seems to have a problem: printing the advertisements does not work correctly. The advertisements function as specified by filters but some networks do not show up. They used to work in 5.8. However using any looking glass from upstream providers the networks that do not show up in ROS 5.12 show up in the upstream routing table. As I’ve noticed only /32 announcements do not show up. We are only using /routing bgp network for upstream advertisements so maybe it’s somehow correlated with that.

Also, the sessions have to be re-established for the announcement to work, this also wasn’t necessary in 5.8.

We are also getting a lot of flapping with our peers. We checked everything, it’s ROS related for sure.

Can someone else check/confirm these bugs?

Also, sometimes the routers simply stop working. SNMP is not working anymore and Winbox logs in but shows nothing. During that time /system reboot does not work. The systems have to be rebooted by the reset button.

If we try to remotely reboot them we get:

/system reboot
Reboot, yes? [y/N]:
y
system will reboot shortly
login as:

But there is no reboot.
Again this is happening on multiple systems, which have different configurations so there seems to be a bug in this version which is causing this lack of stability and responsiveness.
