Hi Sumit,
What is the version of Virtuoso being used:
./virtuoso-t -?
What are the datasets being load and the expected triple count ?
What does the output of running the Virtuoso status command run from isql
report ?
When you complete the loading of the data is a "checkpoint" run to ensure that
is committed to the database ?
Does the "load_list" table indicate that all the datasets where loaded
successfully ?
Best Regards
Hugh Williams
