Hi Stephan, My guess is that the center or radius of the PagedLOD has been set incorrectly so it's being culled inappropriately.
As a general note, I'd recommend up grading to OSG-3.4.0. There are lots of improvements between 3.0.1 and OSG-3.4.0, including to database paging. Whether it will have any baring on the problem you see I can't say, if it is a database issue as I suggest above then it won't help, but the rest of the improvements (features and bug fixes) to the OSG should be useful regardless.
