First I've heard of it. May not be resolved unless a developer can

I think we've finally found the cause of the problem - it wasn't just
occurring after heavy use, but was visible right after filesystem
creation! We regularly built new filesystems with "newfs -U -O 1 -b
65536 -f 8192" (a couple of our older products are still based on
FreeBSD 4, so we built UFS1 filesystems for all our products). It seems
that newfs with the -O1 option creates inconsistent metadata: fsck on a
large, newly-built UFS1 filesystem complains in phase 5 with "SUMMARY
INFORMATION BAD". I've filed a PR on it.
