I believe I have encountered this recently, but didn't get enough
chance to work with it to correspond. For me, the cause was
out-of-disk on the file system that exclusively contained WAL,
backlogged because archiving fell behind writing. This causes the
cluster to crash -- par for the course -- but also an archive gap was
created. At the time I thought there was some kind of bug in dealing
with out of space issues in the archiver (the .ready bookkeeping), but
the symptoms I saw seem like they might be explained by your report,
too.
