I experience hangs of a single ZFS dataset when under low load with samba. Processes trying to operate on the dataset are stuck in ZFS state ("smbd", "ls", etc.), this applies to "zfs umount -f" as well. Other datasets operate without problems. zfs list, set, etc. work correctly with this dataset. A hard reset is required to have the system operating again. This error happened on two systems with different datasets so it is reproducible, I should try to define how to reproduce it. How can I help debugging this problem?
