   @didip thank you for digging this issue. If this is what happened, it could be a bug in the `httpRemote` runner which is the HTTP-based task scheduler in the overlord. The parallel task just uses the same system. Do you see any errors or exceptions in the overlord logs? BTW, please note that the `httpRemote` runner doesn't use ZooKeeper, but uses HTTP to communicate with middleManagers. Dangling entries might be another issue but I assume they are ephemeral nodes and should be fine?
