Can you run this test program? It’s by the database author, and tests a lot of reads and writes in parallel to the database. In practice this tests two things - the code for bugs, and the hardware for problems. I’m running it now on a few machines and haven’t seen any issues so far. But the database does checksum all it’s data, so memory problems will show up as the error in the topic. I’d be curious to see how it goes on your machine.
