[Bucardo-general] slow swap sync debug?

[Jonathan Brinkman]

I have a swap sync that should only take 3-4 seconds to run, but is WAITING
for 30-45 seconds every time. This causes down-line problems as the user
must wait that long, and thinks something is broken so they "try again"
causing additional problems.
Is there a way to debug a swap sync to see what is causing the delay?
Using bucardo 4.4.8 ubuntu 10.04LTS postgresql 8.4

Every second bucardo is sending a KICK to that sync, and the log.bucardo
repeatedly replies that it can't add to q:
