> EstimatedHistograms used in timers are allocated with 90 buckets, as part of 
> CASSANDRA-16760. It can represent the highest value of 25 seconds. The 
> setting is not free from hitting overflow error when calculating the mean 
> value from the histogram. We can increase the buckets count to 127 to 
> increase the upper limit to 21,356 seconds, which just covers the range of 
> 164 buckets prior CASSANDRA-16760.
