Can't stop sync task

[VictorSTS]

I have a PBS on which there's a sync task running and I would like to stop it, but PBS just does nothing when I try to stop it and the task keeps running. The sync is local in the same server, as part of moving data to another datastore/zfs dataset. The disk are all HDD without any vDev.

The log looks like this:

Eventually, the 2022-10-18T14:18:11+02:00: received abort request ... just dissapears and another snapshot starts to sync. Meanwhile the task is going on, as I see more data being copied into the new dataset.

Is there any way to forcibilly stop the task besides restarting services/rebooting the server?

Thanks.

It took like 35 minutes to stop, but finally did. Seems as if the task has to reach a given point to be able to stop properly. Some feedback about this in the GUI and/or/ CLI would be nice.
