Except that the delay is likely because the OutgoingRunner was
slugishly making its way through the "between 80 and 100 .pck files in
queue/out at this time", each of which is a separate message to be

The question is why is OutgoingRunner so slow as to create such a
backlog or perhaps what happened to dump all these messages into the
queue at once.

Also, there could be an issue with the qfiles/out directory being
physically large even if it only contains a smaller nubmer of entries
now, although that should only affect storing new queue entries, not
retrieving them. See the post at
for more info on this and some other tips too.
