           Summary: [ka-Map] Infinite loop if tile.php produces a MapServer
                    error
           Product: ka-Map
           Version: 1.0
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: core
        AssignedTo: ka-map-dev at lists.maptools.org
        ReportedBy: dmorissette at mapgears.com


If tile.php is pointed to a mapfile that contains errors (e.g. syntax error, or
any MapServer error that results in no image being produced) then ka-Map tries
fetching the tile again using force=true ... which will fail as well ... and
then we try again ... fail, try again, fail, .... and this infinite loop can
eventually take the server down.

I don't know the ka-Map javascript code, but I think the solution would be to
have a limit on the number of times ka-Map tries to reload a tile before giving up.
