> I have a pool of 3 and have several jobs (over 10) which use the pool.
> Tasks timeout (after 10 mins) from being stuck in scheduled state when the tasks should be in queued state for the pool.
> to reproduce:
> use attached dag, and create a pool called "backfill" with 2 slots
> start the dag, and go to this url - >
> <your_server_addr_here>/admin/taskinstance/?flt0_pool_equals=backfill
> you'll see two light green "running" state, loads of white "scheduled" state and none in grey "queued" state.
> what I expect would be two in running, the rest in queued state.
