Performer Culling things it shouldn't.

I have encountered some very odd behaviour with the culling
in my performer application. First of all my application is a simple
flight sim. When I am flying through the terrain alone everything
works fine. However, when I start receiving other players (via a
network interface) the culling messes up. When my view's pitch
and roll are near zero (+ or - 5) the entire scene graph is culled,
otherwise it runs correctly. My scene graph is organized into
two main parts Terrain( which contains all of my terrain patches)
and RemoteEntities(which contain a couple hundred instances of
1 or 2 models) both of these groups are children of root. I was
using a Traversal Mode of PFCULL_ALL, I tried using
PFTRAV_GSET and I had no problems, except that my application
ran much slower. Based on this I am assuming that Culling is the
problem.
Has anyone encountered this problem before? Any help is appreciated.
BTW I am using Performer 2.1 on IRIX 6.4, on an OCTANE with
MXI graphics. Thanks.
