If you are willing to go all-out, you can probably catch the
error with strace, if it works on ARM. Failing that, find all places
where 507 is generated and see if any exceptions are caught, by
modifying the source, I'm afraid to say.

That's a possibility. Or, it could be a kernel bug. You are using XFS,
right? If it were something other than XFS or ext4, I would suspect
ARM blowing over the 2GB barrier somewhere, since your object is
called "bigfile3". As it is, you have little option than to divide
the layers until you identify the one that's broken.

BTW, make sure to disable the fallocate, since we're at it.
