<P><FONT SIZE=2>Bart,</FONT>
</P>
<P><FONT SIZE=2>Is your ECW file larger than 2GB?</FONT>
</P>
<P><FONT SIZE=2>There is a problem in all released versions with fopen() failing on large</FONT>
<BR><FONT SIZE=2>files, so the attempt to "try" shapepath seems to fail to MapServer even</FONT>
<BR><FONT SIZE=2>though the actual ECW file would have opened ok.</FONT>
</P>
<P><FONT SIZE=2>There was a bug submitted on this, and a patch has been applied in CVS</FONT>
<BR><FONT SIZE=2>(on the 4.8 branch as well) so the next releases on 4.8.x and 4.9+ should</FONT>
<BR><FONT SIZE=2>be corrected.</FONT>
</P>
<P><FONT SIZE=2>This will also affect other GDAL supported formats where the actual file</FONT>
<BR><FONT SIZE=2>is more than 2GB. It only affects SHAPEPATH use though. Direct access</FONT>
<BR><FONT SIZE=2>always works ok.</FONT>
