A climbing L1011 without TCASII and a B767 level at cruise with TCASII avoid each other by 600 ft when the single TCASII warning was activated. It is alleged that the controller had spent the preceding 5 mins having a personal conversation with another aircraft.

Narrative:
Climbing to FL350 at FL334 saw a B767 at a real close vertical distance. He was level at FL330. A B767-800 had a TCASII resolution to descend to FL320. We did not have TCASII equipment. The contributing factors were that maiquetia traffic controller was at that time talking to a friend on the frequency for over 5 mins and failed to give us any TA's. When I questioned his mistake, he said that the radar was out on that area.
