Sounds like it. I'm still not clear what happened in the run up to 
this. Am I right in thinking you...

* Wait until a client is backing up to a server

* Kill the server bbstored process (letting the sub-process which is 
handling the client remain)

* Delete all the data from the server

* Restart the bbstored process.

If this is the case then I need to

1) Finish the server side recovery tools, and release them

2) Adjust the behaviour of the servers to signals, so sub-processes end 

and you need to wipe your entire server configuration (keeping a copy 
of all the *.pem certificate files) and then start again.

Unless you start from an absolutely clean setup, I'm not sure there's 
much point in me looking into this too deeply. I can see exactly how 
this state could come about if I'm right in how you got here.

In an error state, there will be connections every 100 seconds or so. 
In normal operation with the default configuration, you would expect 
one every hour, unless no files had changed, when it wouldn't connect 
at all.

Maybe. :-) There's more important stuff to do at the moment.
