Hi Dimitris
What is happening on the Virtuoso server side as the Virtuoso error is
"Virtuoso Communications Link Failure (timeout) : Connection to the server
lost" , so does the server crash and have to be restarted or is it the JDBC
client the is crash when some operation is performed ? You can turn tracing on
on the server with "trace_on()" [1] to get extra information in the Virtuoso
log as to what are the last operations being performed. You can also enable the
"CallStackOnExcpetion"[2] INI file param to potentially obtained more detailed
errors on the client side.
Best Regards
Hugh Williams
