I think the problem is in the number of layers that can be allocated by =
its "Struct".

Any thoughts

  Subject: [Mapserver-users] Max number of layers craps out at about 295


  Hi all,

  I am trying to get the max number of layers that MS will read from a =
*.map file to be 500 or more.

  Once I exceed about 295 layers the MAP file will not be displayed.

  The error I get is 'The Memory could not be "read".' with some hex =
codes displayed.

  I have attached my "map.h" file as reference.
  Is there some other file that have to modify to be able to increase =
the number of layers?

  thanks
  Stephen
