Do you have lzjb compression in your pool?
My pool does use it (on some filesystems) and it's also almost full (95% used).
'zdb zroot' fails with 'assertion failed' message.

1089791    1    16K    64K    64K    64K  100.00  ZFS plain file


Traversing all blocks to verify checksums and verify nothing leaked ...
Assertion failed: (space_map_load(&msp->ms_map, &zdb_space_map_ops, SM_ALLOC, &msp->ms_smo, spa->spa_meta_objset) == 0), file /work/opensource/OS/FreeBSD/current-gem/cddl/usr.sbin/zdb/../../../cddl/contrib/opensolaris/cmd/zdb/zdb.c, line 2115.
zsh: abort      zdb zroot
