I was able to see opensolaris snv_134 to become unresponsive due lack of memory with nested pool configuration today. It took around 12hours issuing writes around 1,2-1,5GB/s with system that had 48GB of ram. Anyway, setting zfs_arc_max in /etc/system seemed to do the trick, seems to behave like expected even under heavier load. Performance is actually pretty good.
