Yes --- that indicates the end of archive. It sounds to me like file 1B
was archived while still only partly filled. Check the process you're
using for deciding when to copy WAL files.

I think that's expected behavior --- it has something to do with wanting
to make the copy of 1B into the new writable front WAL segment. You can
dig through xlog.c if you want the details.
