Description

Metric admission-controller.executor-group.num-queries-executing.* should not go negative at any time. However, we have seen some occurrence where this metric value goes negative under certain executor crash scenario.

We need to investigate how to reproduce the crash scenario and mitigate the negative metric issue.
