Hi Sarala, Is there any error written at the end of the virtuoso.log file at the point of the crash and is a core file created whose stack trace can be analysed to determine point of the crash ( shall "ulimit -c" needs to be greater then 0 for core file creation) ?
What happens if you execute the same query against the Virtuoso SQL interface (port 1111 by default), which is the interface used by the Jena Provider as opposed to the HTTP (8890 default) used by the sparql endpoint, using the Virtuoso command line "isql" tool ?
