> The help for linearstore parameter wcache-num-pages indicates that legal values are powers of 2 between 1 and 128. In addition, the validation for this parameter allows these values. However, the minimum value should be 4, and using either 1 or 2 as a value will cause a floating point exception when the broker is started.
