Andy Seaborne commented on JENA-1138:
-------------------------------------
This may be already fixed recently in DatasetUtils.addInGraphs which is now
transaction sensitive.
> java.lang.OutOfMemoryError: GC overhead limit exceeded

> Key: JENA-1138
> URL: https://issues.apache.org/jira/browse/JENA-1138
> Project: Apache Jena
> Issue Type: Bug
> Components: Cmd line tools
> Affects Versions: Jena 3.0.1
> Environment: Oracle JDK 1.8.0, Windows 7 64bit
> Reporter: Giovanni Mels
> Labels: performance
> Attachments: sample-data.zip
>
>
> Since 3.0.1 we get {{java.lang.OutOfMemoryError: GC overhead limit exceeded}}
> exceptions when using the {{sparql}} command line tool, even on relative
> small datasets (~1.6 million triples).
> The issue occurs when the dataset is loaded in memory, so before the actual
> query execution.
> {code}
> sparql --query empty.rq --data sample-data.ttl
> {code}
> Where {{empty.rq}} contains:
> {noformat}
> SELECT * WHERE {}
> {noformat}
> This query takes ~20 seconds using Jena 2.13.0 and Jena 3.0.0, it fails with
> 3.0.1 after ~4 minutes with {{java.lang.OutOfMemoryError: GC overhead limit
> exceeded}}
