Hi Steve, Thanks for the update. I suspect you have gotten TDB locks in your workspace from the abrupt restart of the server.
Shutdown TopBraid and go into your workspace and looking for these locks and remove them as with anything, backup your workspace first: sudo cp -a /var/lib/topbraid/ontologies /var/lib/topbraid/ontologies-14Dec2017 now lets find and remove locks if there are any. cd /var/lib/topbraid/ontologies find | grep tdb.lock if you have some, remove them like so rm -rf $(find . -type f | grep tdb.lock) once the tdb locks are removed, restart TopBraid On Thu, Dec 14, 2017 at 12:46 PM, Steve Ray <[email protected]> wrote: > Nick, > > No, we’re using the built-in triple store that comes with TBL. > It’s not relying on any other software package.
