Hi Ankit,

Have you been successful so far? You can have a look at two stress tests that I've just added [1,2]. In the tests, up to 10'000 documents are added to a database by multiple threads/clients

Best, Christian

Hi Ankit,

I guess you are working with the latest version of BaseX? Could you please provide us with some code that allows us to reproduce the bug?

Thank in advance, Christian

Hi,

We are adding number of documents concurrently to the Basex database using basex java api. Our application runs three threads in which each thread is adding documents to it by executing following instructions in java as given below.

new Add("",new File(source).getAbsolutePath()).execute(context);

while running our application sometimes throws the following error
