Is this an issue

No issue, normal behaviour.
As long as your responding to challenges fast enough I wouldn’t be concerned.

As long as the secon side shown here is 5 and below 5, I think there is no problem, I think better masters can answer

I agree with @west_77, anything 5 or below is not a problem as long as the frequency of these messages is low.

For me, this shows up 16 times per day on average with the validation time all between 2 and 3 seconds. If you’re seeing this many times in an hour, something is slow. Most likely the disk storing the blockchain is the bottleneck (slow or very busy), but since block validation is in question it could be a busy CPU.

Thanks for the replies…
