    If something goes wrong in the middle of an update, Hudson gets stuck and never recovers without manual intervention. After a failed build / update last night, the following exception was thrown on every subsequent build. The fix was to delete the files in /var/tomcat0/.hudson/updates/* Ideally, Hudson would be able to recover from this on its own.
