Hi,
Yes I have a lot of trouble with zfs send .. zfs recv too.
(sol 10 6/06, SUNWzfsu 11.10.0,REV=2006.05.18.02.15). All too often there is
panic of the host doing zfs recv.
When this happens for a certain snapshot combination ie zfs send -i snapA snapB then it *always* happens for that combination. In my experience about 1 combination in 30 leads to a crash. This might not seem very frequent but i'm using zfs to try to keep in sync a server with an on-line backup host with a dozen or so filesystems every 2 hours.. and inevitably i get a crash every day. These panics are very inconvenient and given that some combinations of snapshots never work I have to rollback a step or two on the backup server and then try another snapshot combination to move forward again. Tedious!
My core dumps look a bit different though (but always in same ...)
