[gradsusr] Critical bug: "Memory allocation error: gxhpng" when drawing shapefiles

[Stefan Gofferje]

Hi,

I had a HD crash in my server which killed the directory where I had the
shapefiles. I downloaded all shapefiles again (from DIVA and natural
earth), put them in another folder, modified the rendering script
accordingly but now I don't get any shapes any more. The plot is
outputted with everything that's plotted, just the shapefile information
is missing. (s. http://www.saakeskus.fi/24h-precipitation-forecast#top).
The log shows only that error "Memory allocation error: gxhpng" after
each plot.

The script that draws the maps is attached. Normally, I use it like this:

'run sg_shapemap finland1'
...
plot all kinds of stuff
...
'run sg_shapemap finland2'
'printim '_webdir'/filename.png '_imagesize' -f '_stamp


>From what is going on, my guess would be that something has changed in
the shapefiles that grads can't deal with anymore.
For me that's a disaster because it breaks the most popular charts in my
website.
I already upgraded from 2.0.0 to 2.0.2. My rendering system has 8GB RAM
of which is most unused, sop it shouldn't be that.

ANY kind of help would be very welcome because now the stormchasing
season has started and my most popular and most useful charts are gone...

Greets,
Stefan
