If it only complains once per file name, this is expected behavior when
somebody drops a table just before the checkpoint mechanism tries to
fsync it.  (If the failure were to repeat, then it might be something
more interesting.)  It does seem a bit odd that only fsm files are being
complained of, though.

What PG version is that exactly?
