Ciao Luca,
I had earlier documented by usual PostGIS debugging steps at
https://mapserver.org/optimization/vector.html#debugging-speed-issues-with-postgis
Also, instead of the "-map_debug 3" option with shp2img, try "-all_debug
5" (use "3" if you just want to show the draw speed times)
The goal would be to output the exact query that MapServer is trying to
execute against your database, and then try running that query at the
psql commandline.
And, if all else fails, be sure to retry all of this with a build of
today's MapServer "main" branch, and try with map2img.

Hi all,
I'm getting "Floating point exception" error running shp2img, also
running with the debug option I don't get any other information.
The mapfile read data from PostGIS database, and If I use the same
mapfile with different database with the same tables I don't get this
error, so I think the problem is in the data but I don't know
where/what investigate
thanks in advance
