This is the second report of a smallish filesystem using all of the
system's memory (the other being xfs_repair). Hopefully when I diagnose
the problem with the previous report, I can fix the same issue with
xfs_db and your filesystem.
If it at all possible, can you xfs_copy the offending filesystem to a
file and compress it and make it available to me to find/fix the
problem.

Your files have been restored as much as possible. You'll have to work
out what is in lost+found and move them back to their appropriate
locations.

No, this shouldn't be causing the xfs_db strange behaviour, but the
nlink count mismatch is a problem with xfs_repair 2.8.11. Try and use
xfs_repair 2.8.16 and later to fix this issue. Older versions before
2.8.11 will also fix the nlink issue.
