FWIW, I had this happen to me several weeks ago on FreeBSD/powerpc64 =
9-CURRENT.  I had to get the machine up and running so I simply =
abandoned use of SU+J and went back to using just UFS+SU.  (Not very =
helpful, I know, but there you go.)  I figure it is likely to be some =
kind of endianness problem in the SU+J code, given the lack of =
complaints on FreeBSD/i386 and FreeBSD/amd64.

Cheers,

Paul.

PS: The system I was using is an Apple Xserve G5 with 4 GB of RAM and 5 =
GB of swap space.  As you say, surely fsck can't be using that much =
