Hi there,
If you get a core dump, the JVM has crashed and it's a platform issue.
There isn't anything in Jena that can cause this - it's pure java. All
the event log seems to say is that some parts of Jena were JIT'ed just
prior to the crash.

I am getting a core dump. It is not always occurring. I am doing a
performance test on a java application. A python script is executing the

cannot say for sure if its because of Jena but this is what appears in
the compilation events:

The entire log can be found in the attached file. Any reason why this is
occuring ?
