Paolo,

I don't think this problem is specifically related to pmapper. It looks 
like a low level problem of Mapscript. Have you tried to run the same 
requests with the same layers via the CGI or shp2img?

Have you tried a very simplistic/generic PHP Mapscript application like 
the one I put in the source as 'test_mapfile.phtml'?

Have you tried if the problem still occurs if you use PHP via CGI 
instead of an Apache module?
