HI Carl,
	The quickest and ugliest fix would be to stop the server, delete the  
"workflow-data" directory from that project, and restart.  Somewhere  
in that directory some of the data is in an inconsistent state due to  
the forced shutdown, and I can't seem to ssh in to track it down.   
Deleting the workflow data directory will wipe out all records of  
past workflow activities (build, publish, etc), and will kill any  
approval requests currently outstanding.    For many sites this isn't  
a big deal.  If you don't want to lose those records, or if you have  
time to explore further, I suggest you ssh into the server and look  
beneath the workflow-data dir for files with 0 length, or any files  
named "file.lock" which you can then remove.  Also, if you want to  
zip up the repository from the command line and make it available to  
me via some URL I might have more luck digging into it.

You're right that there's no shutdown script - if you're starting up  
from the Ant script, just type "ctrl-c" in that window to do a  
graceful exit or do a "kill -15" on the process.  If you deploy it  
into a separate tomcat, you can use tomcat's shutdown script.

Cheers,
Alex
