From time to time I am getting another panic in the same environment as
described in the thread titled "panic: solaris assert:
ba.ba_phys->bt_bytes == 0 (0x400 == 0x0)".
Judging from blk_prop value of 0x8009090200070007 the affected block
belongs to ZIL (type 9).
Some info:
Solaris(panic): zfs: allocating allocated segment(offset=3011224576
