1418	Conversion of MrSID datasets from NASA Zulu to JP2ECW hangs	mloskot	warmerdam	"{{{
During tests of MrSID to JP2ECW translator, some issue has been discovered when trying to convert big MrSID images downloaded from NASA Zulu server.
The conversion process hangs for 2-3 hours with 100% CPU time but without any progress of the translation process.

Here is the full command line using GDAL utilities from FWTools 1.1.0, on Windows XP:

gdal_translate -of JP2ECW -co ""LARGE_OK=YES"" N-35-50_2000.sid out.jp2

Mark Sheridan noticed the same issue when trying to convert images from the NASA Zulu server. Mark and I tested on different images from the Zulu server, so it seems does not depend on a particular image but it applies to all images from Zulu server. Thus, It should be sufficient to download any image from the Zulu:

I'm going to attach two screenshots taken at the beginning and at the end of the conversion process.
