Hi,
do you check the memory_limit Parameter in php.ini?

-possiblesolution for some problems


Hi all,

I want to confirm your mailing ;-)  (Okay the date of the mailing is
August 2007!, but)

I just had some troubles printing DIN A0 PDF's with mapbender.

The last problem to solve: Increase the setting of
default_socket_timeout in php.ini !

(Sometimes printing DIN A0 was okay. Sometimes only the frame (and
overview and legend) was printed. But the map itself was empty. I
observed, that printig DIN A0 was okay, if the filesize of the mapserver
- generated png had less than e.g. 60MB (e.g. a black&white layer). If
file size was greater than 60MB (e.g. a colored layer), the print failed
).


regards
Herbert
