"Deleting unreferenced location with LID" endless loop when deleting node

When I delte a node, Drupal seems to go into an endless loop. I get an timeout error from the server and in the logs I see hunderts of entrys like:

"Deleting unreferenced location with LID 11945."

I have Drupal 6.24, Location 3.2 and (if that matters) CCK 2.9

this behaviour now occured after we moved to a new server.

I hope anybody can help..
