Do you have some kind of automatic updates enabled? How often dou you
restart? Any live patching enabled? Seems like Python calling into
libc is the problem:

> return libc.llistxattr(path, buf, size)

https://github.com/borgbackup/borg/blob/1.1.17/src/borg/xattr.py#L219

Your problem is with handling some symlink:

> llistxattr() is identical to listxattr(), except in the case of a
> symbolic link, where the list of names of extended attributes
> associated with the link itself is retrieved, not the file that
> it refers to.

https://man7.org/linux/man-pages/man2/listxattr.2.html

So increase verbosity of BorgMatic to show all processed individual
files and have a detailed look at hopefullx the last one mentioned
before the stacktrace. Something around the following:

> --log-file-verbosity 2 --files

Mit freundlichen Grüßen
