<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">Hi, Stephen -- <div>The error message you're seeing occurs when the printim code tries to allocate an array that contains the vertices of a filled polygon. It may be that your shapefiles have single polygons with so many vertices (e.g. the one that fills in most of Canada) that your 3.2Gb of RAM is not enough, or maybe an integer isn't big enough to represent the number of elements in the array, so it passes malloc some junk and you get an error. To complicate things, you are also using a deprecated shapefile interface that I didn't write. </div><div><br></div><div>See if you can reliably reproduce this error with the latest COLA version of GrADS. If so, then send me the simplest possible script and the required shapefiles, and I will try to reproduce the error on my own system that has lots and lots of available memory. </div><div>--Jennifer</div><div><br></div><div><br><div><div>On Dec 1, 2010, at 6:38 PM, Stephen McMillan wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div>John,</div>After a full reboot, I re-ran script but with same memory allocation error.
