      There is a TOCTOU bug in the code of KillSessions command: The cursorMap mutex is not held while each cursor is being killed. It is possible that a KillCursors command jumps in and kills a cursor which will be but has not been killed by thisĀ KillSessions. KillSessions will then get a CursorNotFound exception.
