There was an error in my code, I fixed it.
Now I am not getting errors on client side, but BaseX is not persisting all documents that I inserted.
I created 20 BaseXClient's, 10 threads to take BasXClient from a LinkedBlockingQueue, each thread was
responsible to insert 1000 documents, total of documents 10 x 1000 = 10K, however was inserted 9801.

Hi Willian,

thanks for your mail. I would assume that one single BaseXClient
object was used for several concurrent tasks. As BaseXClient objects
are very light-weight, and as the registration of new clients is
usually more than fast enough, the usual approach is to create a new
BaseXClient instance for a dedicated action.

Hope this helps,
Christian
