Thanks for the tip. Out test has so much logic, testing of search results, comparing stuff etc, so we decided to build it with PHP.


But from Jmeter got an idea, is it possible to save all calls to Jena (with content, headers) so that it's possible to rerun the test without our environment?

Maybe you can make a reproducible using JMeter or such.

Yes, clean install of Ubuntu, Jena etc.

We are using GSP and our test script is doing ~20 json-ld inserts and

Starting with an empty database?

"fairly high load and concurrent usage"

This is not a very precise or reproducible measure.

Many sites use Jena in production at all kinds of scales for all kinds
of dimensions, including HA setups. If you can explain more about your
specific situation, you will get more useful advice.

To be clear: can Jena be recommended for production database in our
customer cases for fairly high load and concurrent usage? Or is it mainly
for scientific purposes?

To my knowledge (Andy of course is the TDB expert) you can't really
rebuild a TDB instance from a corrupted TDB instance. You should start with
a known-good backup or original RDF files.

I'm going to rule out corrupted database on our oldest server. What
would be preferred way to rebuild data?

These seem to be different errors.

"In the middle of an alloc-write" is possibly a concurrency issue.
"Failed to read" is possibly a previous corrupted database

This is a text dataset? That should be using an MRSW lock to get
some level isolation.

What's the Fuseki config in this case?

On the latest 3.7.0-Snapshot (master branch) I also saw repeated
occurrences of this the other day while running some queries from the
fuseki browser app and with a database load going on with our own app using:

with for the first model to transfer:

       DatasetAccessor putModel(graphName, m);

and for following models:

       static void addToTransferBulk(final String graphName, final
Model m) {
           if (currentDataset == null)
               currentDataset = DatasetFactory.createGeneral();
