Router stop forwarding traffic after 100 days uptime and operation

It seems that I had a very bad experience with Mikrotik today. One of my router stop routing traffic causing part of my network to lose routing connectivity to a local Internet Exchange. I had to reboot a few times before the BGP peer can be established.

Is anyone facing similar problem?

Not moving to the latest release till 6.29 is out and tested in our development lab.
