          It stuck in "init for update" state using Aria engine too but only for 10 seconds same query on InnoDB stuck for 3000s (killed after 600s)

          Tested 10+ times always 10s in "init for update" state.

          Setting optimizer_max_sel_arg_weight=320 with InnoDB/Aria query is executed very fast. 3200 produce short stuck in "init for update" state.
