ZFS stuck in zfs:&buf_hash_table.ht_locks[i].ht_lock]

Hi,

It seems that with a lot of file on ZFS (used as / but I don't think
this would make change) w/ compression configuration, the nightly
locate(8) scan would finally cause the box to enter a livelock/deadlock
where locate would stuck in 'zfs:lo' state, and new process accessing
the file system would stuck in 'zfs:&buf_hash_table.ht_locks[i].ht_lock]'.

Is this a known issue (any workaround)?  This is a production box
without serial port, and is several miles away from me, but I will try
to provide some debugging aid if necessary.

Cheers,
