Yes，I opened it.
This bug can only be triggered when the single replica optimization takes effect.

Could you explain it more?

Could you explain it more?

When enable single replica load, there is only one channel for a tablet, but the number of failed channels used to determine whether it is an intolerable_failure is calculated based on the actual number of replication, which means that even if the all tabletChannel fails, the load task will not fail.
