Currently it's not possible to run multiple concurrent vibe-jobs using a single database (TDB). To allow for concurrency, currently multiple identical TDBs are needed for each individual concurrent JVM. To enable concurrent usage, support for Apache Jena Fuseki could be added. Alternatively, SPARQL queries could be used only for the initial export of data and then be migrated to a different type of database.
