Launchctl hangs on loading plist

Please help.

I'm just trying to migrate my plist jobs to a new Mtn Lion server. EVERY time I try to load a plist, launchctl just sits there. No errors, no return message, no log message, no nothing. I eventually have to Ctrl-C out of it to get it to return to a prompt.

Has anyone seen this? I can't find any mention of it on the web. Thanks in advance.
