Unfortunately it's not easy to trigger and I don't have a spare machine, so I had to reboot to get it back into operational state, hence no root cause findings yet. Just a rare-regression heads-up... (still suspecting zfs with no hard evidence yet - machine has plenty of resources (64GB w ECC, 1TB single-NVMe vdev zpool with at least 60GB free space) - top/systat etc. showing nothing suspisios, just heavily slowed down I/O up to 'bad file descriptor' failure; maybe https://lists.freebsd.org/archives/freebsd-stable/2025-October/003532.html is related?)
