> BufferOverflowException when

> Key: JENA-1581
> URL: https://issues.apache.org/jira/browse/JENA-1581
> Project: Apache Jena
> Issue Type: Bug
> Components: TDB
> Affects Versions: Jena 3.7.0, Jena 3.8.0
> Environment: Jena 3.8.0
> Reporter: Scott Patterson
> Assignee: Andy Seaborne
> Priority: Critical
>
> I can not add a small number of named graphs (~1000) to the TDB without
> encountering a BufferOverflowException. I have a single thread that adds all
> the graphs and I get lots of these exceptions with different named graphs
> each time. Any thoughts?
