Well.. it could have been just some coincidence :-)
I found the errors should blame to something about inode_extref check
in lowmem mode.
So you mean errors in btrfs-check... and it was a false positive?
Not so perfect original and lowmem mode of btrfs-check are.
I need to figure out what is on the actual FS, may a false alert or
actual error.
I have writeen three patches to detect and report errors about
inode_extref. For your convenience, it's based on v4.17:

I hope I can test them soon.... could take a bit longer as I'm about to
head off into vacation.
Fine, of course. Enjoy it :)
Thanks,
