[Mapserver-users] PERL mapscript undefined symbol woes

Red Herring alert!!

I believe that the undefined symbols are set by the encapsulating 
instantiation of PERL.  This is not my problem.  The real problem 
resulted from a change in one of my shapefiles.  The updated file 
contains a significantly larger number of points.  My current working 
theory is that the number has somehow exceeded a fixed limit.

Cordially,

Joe Bussell
