Rob Vesse commented on JENA-1927: --------------------------------- Note that this is an error message from a low level sub-system. At the point the error occurs it has absolutely no idea the context in which it was called so it can't blindly add any verbiage about how to resolve the error because it depends on how the low level sub-system is being used. That being said the website could have more information about this, added to FAQs with PR https://github.com/apache/jena-site/pull/13 > First time usage confusing message Unable to check TDB lock owner, the lock > file contents appear to be for a TDB2 database.
