My memory is a little uncertain, and I can't find a solid reference, but I
think you can use "xfs_repair -n" in place of xfs_check, without making
any changes to the FS, and xfs_repair is less memory intensive.
I'd be pretty worried operating a file system that had grown beyond the
limits of what the FS check utility can handle.
