I've been setting up CruiseControl for the first time and have been getting hangs when using the cruisecontrol/project/publishers/execute element.
It seems to be related to the amount of output from whatever command I call. I deduced this by changing a script that was causing a hang to echo less output and the problem went away. Redirecting the output to a file does not fix the problem.

This happens in 2.8.2 and 2.8.3 with JDKs 6, 5 and 1.4. I'm running on Windows XP.

Is this a known problem? Does anyone else have the execute tag working reliably?
