Looks like DRILL-5547: Linking config options with system option manager ( https://github.com/apache/drill/commit/a51c98b8bf210bbe9d3f4018361d937252d1226d ) introduced a change in the computation, which is based on the number of cores. https://github.com/apache/drill/blame/6ad9838339999c3e069b6925d0c3ce3077afd8c3/exec/java-exec/src/main/java/org/apache/drill/exec/server/options/TypeValidators.java#L252
Looks like a non-zero value is not being computed. Setting the value as a system variable should persist and correct this. Can you file a JIRA for this? The fix should be minor.
