Lets see, I have about 12 RB232's and 3 RB500's. Since 2.9.13 OSPF has been problematic. We upgraded to 2.9.14 to FIX the issues from 13 and our OSPF crashed and any router with more than one ospf partner in our case 9 of them had flapping interfaces and would not form adjacencies and did not pass traffic.
This means for my network that over 2000 customers did not have service. We spent the better part of a day thinking it was hardware, and then when new hardware did the same thing, we decided to roll back to 2.9.12 on the core 532's and they stabilized.
The next morning, ALL of my RB232's running 2.9.14 were down so we had to power cycle each tower so they would come back up then we downgraded to 2.9.13 as I did not have a copy of .12 for the 232.
This morning AGAIN one of the hub towers with four attached towers or 600 customers was down again and the interface on the neighbor router showed 12000 state changes in four hours. We bounced it and it is now downgraded with 2.9.12 we pulled from the archive page.
I would consider every tower on my network failing after the 2.9.14 release a significant reason to change.
I appreciate the support from this forum and I thank those that contribute, but even Mikrotik sent a warning about 2.9.14 yesterday and the 532's, but we have this issue across the board.
I am now downgrading every router to 2.9.12 when it was last stable and we are planning to remove the mikrotiks from our network and move to something that can handle the load we place on the hardware.
Again I thank everyone for their support.
