We have a high cpu on our RB230 board once we upgraded it from 2.9.51 to 3.4. We thought that this could have been jsut a random fluke and then noticed one of our other 230 borads doing the exact smae since it was upgraded to ROS 3.4.. Any clues? Is this a known problem? I do not see any bug fixes for us to go onto 3.6 so we have down graded to 2.9.51. In doing this down grade all of our WLAN cards were reset to defaul configurations. Lukily we had enough information to revert evertyhing back. Nonetheless if you have a RB230 board it seesm best not to have ROS3.4 or greater on it yet.

Here is our graph(it is the exact smae for our other graph for the cpu on our other RB230:

Hi - I have a mesh of about 50 RB532s and recently upgraded
a bunch of them to ROS3.7. On most (if not all) upgraded nodes,
CPU usage has gone from 0-20% to 80%-100%. The network is
a simple single path bridged 5.8GHz wds configuration with 3x 2.4GHz
APs/VAPs per node. I'm considering downgrading all to 2.9.51...
Any ideas/suggestions?

Do a /system check-disk first.
It helped for me in a few cases.

Thanks - here is a solution I came up with. I submitted
a support request which Mikrotik has poo-poo'ed it but it
worked for me:
