PHP/Mapscript still has a memory leak

[Stephen Woodbridge]

Hi Daniel,

I just updated to mapserver nightly (Aug 9, 2006) and I'm running the 
ka-map precache2.php modified to run in apache. The previous fix to 
solve the leaking file handles improves things greatly, but there is 
still a memory leak.

If I restart apache and fire off the script it uses a modest amount of 
memory, under 300MB for the process. Since I'm running 25000 scale, it 
runs a long time, and after 24 hours the process is using over 1GB of 
memory.

I can send my copy of precache2.php if that would help. The mapfile uses:

   OUTPUTFORMAT
     NAME PNG8
     DRIVER "GD/PNG"
     EXTENSION "png"
     MIMETYPE "image/png"
     IMAGEMODE RGBA
     TRANSPARENT OFF
     FORMATOPTION "QUANTIZE_FORCE=ON"
     FORMATOPTION "QUANTIZE_DITHER=OFF"
     FORMATOPTION "QUANTIZE_COLORS=256"
   END

I assume this is reproducible with any mapfile. I'll write a bug on this 
also.
