[Bucardo-general] bucardo5 sync stops although says "Good"

[Jonathan Brinkman]

Greetings
Using Bucardo 5.1.1 with Ubuntu 12.04LTS and PG9.3.
I have 3 syncs on this system and one of them (a Source / Target sync) keeps
stopping without explanation.
It says "Good" and "Active" but it is not running.
If I use bucardo stop/start it will restart, resynchronize, and stay running
until the next stoppage.
Any ideas why this sync quits but says it's "good"? validate says OK
Only affects this sync!

Also I can't find the bucardo.warning.log file anywhere after converting
from Bucardo4 to 5. Where is that?
Many Thanks!
JB
