[gdal-dev] gdal_translate .vrt issue

[David Fawcett]

I am using gdal_translate and a .vrt to take 115 .jp2 files from the USGS,
pull them together and then export a lower resolution .jp2.

This is with GDAL 1.10 on OSX.
gdalinfo --version
GDAL 1.10.1, released 2013/08/26

When I run gdal_translate, it gets about 30% of the way through the process
and errors out saying that it can't open one of the .j2w files.  When I run
gdalinfo on the file, I can open it, and if I run gdal_translate on just
that file, I can successfully export a reduced resolution copy.

The output of gdalinfo is here:
https://gist.github.com/fawcett/beead31741e24394b38e

I can also load the .vrt image into QGIS 2.2 and it loads (slowly of
course).

Does anyone have a suggestion on how to troubleshoot this?  I am wondering
if I am just running out of memory.

Thanks,

David.
