Hello
(copy of
https://stackoverflow.com/questions/46912359/virtuoso-crash-search-c326-box-serial-length-not-supported-for-data-type)
I am connecting to a Virtuoso 7.20.3216 compiled and installed inside a
VirtualBox CentOS 7.3 64bit, using the RDF4J Virtuoso adapter.
I try to load a Turtle file in Virtuoso using this code :
|Repository r = new virtuoso.rdf4j.driver.VirtuosoRepository(url, login, password); RepositoryConnection connection = r.openConnection(); ByteArrayOutputStream
baos = new ByteArrayOutputStream(); // Turtle data written inside baos String graphUri = ... ; connection.add(new ByteArrayInputStream(baos.toByteArray()),
RDF.NAMESPACE, RDFFormat.TURTLE, SimpleValueFactory.getInstance().createIRI(graphUri)); |
Virtuoso crashes (stops) with the following logs :
|12:10:01 box_serial_len called with dtp 225 12:10:01 /usr/local/virtuoso-opensource/bin/virtuoso-t() [0x8c6d3a] 12:10:01

The same Turtle string, when uploaded to the conductor back-office, works
properly. The file is pretty large so I can't paste it here.
We have narrowed down the problem to a character encoding issue. The turtle file contains literals with accented characters such as |"Disque à gravure
directe"@fr|.
We haven't set any character encoding parameters, neither on the Virtuoso config side, nor in the JDBC connection side. We tried by adding |charset=UTF-8| in
the JDBC connection string, with no luck.
- The |charset=UTF-8| is auto added, if it isn't existed in the URL connection
string (in the RDF4J provider)
- To be sure, that you have UTF8 data in the your stream and better to use
|connection.add(new InputStreamReader(new ByteArrayInputStream(baos.toByteArray()), "UTF8"), RDF.NAMESPACE, RDFFormat.TURTLE,
SimpleValueFactory.getInstance().createIRI(graphUri)); |
It seems also that the problem only arises when the database is empty. When the
database already contains some data, Virtuoso does not crash.
Any idea on
1. what the error message means?
2. how to get some additionnal logs ?
3. what could be the cause of the problem?
4. how to fix or work around this?
Thanks!
