Some wierd interaction is occurring. The log showed two attempts to
archive the file, the second one each time failing, as you'd expect. But
two archivers should not be accessing the same data directory.
What were those two pids? Which postmasters are they children of?
Give me some more info and I can probably track down a bug...
