[Mapserver-users] Trouble-shooting again

[woodbri at swoodbridge.com]

Gerry,

One way to debug this type of problem is to do it interactively like 
this at the command shell:

export REQUEST_METHOD=GET
export QUERY_STRING="map=%2Fvar%2Fwww%2Fmesonet%2Ftexas
%2Fmesonet.map&layer=weather-metar&layer=weather-mtemp&layer=weather-
mlabe
l&layer=weather-mdew&layer=weather-barbs&zoomsize=2&program=%2Fcgi-
bin%2Fm
apserv&map_web_imagepath=%2Fvar%2Fwww%2Fmesonet%2Ftmp%2F&map_web_image
url=
%2Ftmp%2F"
gdb /var/www/cgi-bin/mapserv
run
where
quit

This will set up the environment and run mapserv in the debugger. If 
it crashes the "where: will give you a back trace of where it 
crashed.
