Mangle and routes

We have just upgrade from 6.7 to 6.28 in the log we see mangle rule changed and route changed constantly.This was not happening on 6.7.
Any help appreciated

would be great if you posted the actual log, and the rules themselves

Hi Normis,

Here we have a screen grab of the Mikrotik making rule changes and route changes on it’s own accord (totally unprovoked and random):

As regards the Mangle rules, we have no scripts to create, alter or delete mangle rules. The Mikrotik appears to be stuck in replaying a certain subset of instructions. Often we would disable a static route to find that hour later it would re-enable the route without any human intervention.
