Dear Jürgen,
It turned out that the invocation of the INSPECT command raised an exception that was not caught by the command itself, but was only sent to stderr. We’ve revised this with the latest snapshot [1].
Best (and good luck for your power connection in 2024) Christian

Hello,
in our application we "produced" a corrupt data base caused by a power fail. On restart we check data base using the "inspect" command to detect failures, creating new empty data base if found one. The attached data base seems OK using "inspect", but accessing the data base we get an exception. Perhaps this may help to make "inspect" more reliable.
Thanks a lot,
Jürgen Schwenk
