Hi Sarala,
A later 6.1.3 release candidate build can be downloaded from:
ftp://download.openlinksw.com/support/vos/virtuoso-opensource-6-20110105.tar.gz
Can you please download, recompile and test the query again to see if the
problem still occurs ...
Note a Windows 64bit equivalent build is also available from:
ftp://download.openlinksw.com/support/vos/virtuoso-opensource-win64-20101220.zip
Best Regards
Hugh Williams
