I am experiencing a very similar, if not the same, issue.

From time to time, zsysd CPU and I/O usage spikes and stays high for at least 15 minutes. After that, my laptop starts overheating, and I manually restart zsysd using systemctl.

After this restart, a manual run of `zsysctl service gc -vv` cleans old snapshots as expected and takes a very short time, not even a minute. It seems that the previous run that caused the high CPU usage got stuck on some loop.

I am uploading the output of both `zpool` and `zfs list -t all` for the time being.

I have also added this drop-in to the zsysd unit to collect verbose logs for you when this issue reproduces on my side.

# /etc/systemd/system/zsysd.service.d/override.conf
[Service]
ExecStart=
ExecStart=/sbin/zsysd -vv

Is there anything else I could do to help you with this?
