After some errors were logged as to a problem with a ZFS file system,
I ran zfs status followed by zfs status -v...
# zpool status
pool: ehome
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.

# zpool status -v

From another window do a truss of zfs status...
ioctl(3, ZFS_IOC_ERROR_LOG, 0x08041DE0) Err#12 ENOMEM
ioctl(3, ZFS_IOC_ERROR_LOG, 0x08041DE0) Err#12 ENOMEM
ioctl(3, ZFS_IOC_ERROR_LOG, 0x08041DE0) Err#12 ENOMEM

ioctl(3, ZFS_IOC_ERROR_LOG, 0x08041DE0) Err#12 ENOMEM
One would think it would get the message....
After a reboot, a move of the drive to another UFS port on the laptop,
a zfe export of ehome and a zfs import of ehome, it is back on line
with zero errors....
