Hi,
We're setting up a new dev server using Fuseki2 3.7.0 and TDB2. We have
been loading some SKOS vocabularies (e.g. LCSH) into the store via
Fuseki (s-put). We created the database with a then current
3.7.0-SNAPSHOT on 2018-03-28 and switched to the final 3.7.0 soon after
it was released.
Today the database somehow got corrupted. SPARQL queries throw an
exception. We tried to use tdb2.tdbcompact, but it gave the same
exception. Traceback:
12:04:11 ERROR NodeTableTRDF :: Bad encoding: NodeId = [0x
1C1E78F3]

This is not (at least not yet) an important data store for us so at the
moment we just put the corrupdated database aside and created a new one.
But I thought I'd report the problem here in case someone else has seen
the same.
