Hi Andy,
I did some long lasting queries at Fuseki at same time, but dont
remember if that was exactly at the time of error.
Are there some rules whats allowed and not with simultaneous reads and
writes?

Hi Mikael,
It looks like the write transactions aren't able to trigger wring the
journal back to the database. It needs a point in time where there are
no other transactions happening.
Is there a long running read transaction? Or many small ones? going on
at the same time? Or is one write transaction happening at the same
time as another?
