Travis,

Are you using full paths to the files in question.  I vaguely suspect
that the fopen()s used in path construction within MapServer do
not work properly with large files (>4GB).  If that turns out to be
the issue please file a ticket on it.

The work around would be to use a full path instead of depending
on SHAPEPATH or map relative path construction.

Best regards,
