Gabriel,
I have briefly reviewed the MapServer code for reading from OGR and it
does not *look* like a warning should terminate the feature fetching
loop. Would it be possible for you to file a ticket against MapServer
including a simple mapfile demonstrating the issue and a pointer to
the data file? Please ensure it is assigned to "warmerdam" or email
me privately after it is created.
Please be specific about the versions of GDAL/OGR and MapServer you
are using.

I'm guessing that OpenCPN is just less sensitive to the problem in the
data.
Best regards,
