    Description

      The scenario that was registered at customer's site in production includes a batched calshowpartition calls that runs 100-200 `select calshowpartition`. The workload combined with MDB being stopped by OOM-killer(b/c of mem leak in calshowpartitions in 23.02) caused
      multiple connection to SQLSessionThread instance in EM to stuck on a mutex being unable to release it.
