A short reminder of how u can unlock object in XI.
 

I had some objects locked in XI when my computer crashed while i was working in the Integration directory.

U can unlock them by going to the following the directory. As you can see it's a different url for the directory and repository.

Directory:
http://server:port/dir/support/public/LockAdminService

Repository:
http://server:port/rep/support/public/LockAdminService
