> We identified a couple of issues with DaemonSet preemption. The current implementation is not stable.
> Notable issues:
> 1. Flooding the logs from {{tryAllocate()}} because unreservation fails
> 2. Flooding the logs if there are no victims found
> 3. Allocation is stuck if the DS pod cannot run on the target node due to predicate errors
