I do not know if it is related or not: some months ago my FreeBSD 11.2-STABLE box
having GPS received attached at /dev/cuau0 for my local ntpd stratum 1 server
went to late of 2020 insanely. I was forced to comment GPS out of ntpd config to revive it
but I lost all data in hundreds of local RRD databases and
I found a race in libarchive being a reason why my backups had not most part of databases.

I still do not know exact reason and use Internet time source instead of local GPS.
