mountd stuck in ZFS code.

I have been running the experimental nfs/mount for some time now, and it mostly works, except with this particular case, where the mountd just gets stuck: mountd 11762 [dp-dp_config_rwlock] 8.93r 0.00u 0.00s 0% 1320k and stops respondig. I can't reproduce it at will, but it happens quiet
