This sounds reminiscent of issues I had some 6-7 years ago on opensolaris lists (back then). In particular, the seeming culprit was that zfs under-the-hood activities like large pool deletions needed more kernel ram than i had physically available, so after processing some queued operations, the box halted with no mem available (under 32M for several minutes in a row).

It took 2 weeks of reboots for the box to complete its queue of operations (which it did progress, monitorable with zdb -DD IIRC) and a nujber of worried emails to the lists ;)

Not sure your case is similar, but try to track any delayed operations (maybe nowadays via 'zpool get all rpool') to see if progress is being made across reboots. Maybe younjust heec to be patient...
