Hi, I´m in the process of vacating a Sun/Oracle system to a another Supermicro/FreeBSD system, doing zfs send/recv between. Two times now, the system has panicked while not doing anything at all, and it´s throwing alot of SCSI/CAM-related errors while doing IO-intensive operations, like send/recv, resilver, and zpool has sometimes reported read/write errors on the hard drives. Best part is that the errors in messages are about all hard drives at one time or another, and they are connected with separate cables, controllers and caddies.
