Hi Roberto, Hans-Rudolf, I can confirm from personal testing that enabling the parallelism task-splitting in Galaxy does not work well with SQLite.
This caused me problems with development and testing since my development Galaxy instance uses SQLite. As you found, testing with smaller splits is one way round this, to reduce the chances of a database lock. We use PostgreSQL as recommended on our production Galaxy instance with parallelism enabled, and it works nicely.
