ROS v 5.0beta1, CPU@100%

RouterOS General

Hi just had a RB750 tested running v5.0beta1 and have this result:
cpu running at 100% since upgrade, everything becomes slow, latency hits 2digit, and 0 traffic when testing were being done, while none of this happens on 4.6.

Resource the first 57sec:

Oops, downgraded to 4.6 cpu remains 100%… help!!

Try to netinstall a new RouterOS image. That will format the flash and clear out any old config problems that might be stranded from the new RouterOS.
