Hi all, We experienced out of memory error after parsing rdf files. Assuming (or rather guessing?) leak in the jena parsing provider, I implemented a sesame-based parsing provider. However, using sesame-based parsing provider, I also get out of memory error. I carried out some experiments with jena-based as well as sesame-based parsing providers. The results are shown below. There is a memory leak but where? Maybe during storing the triples into the mgraph? I'll check this tomorrow... too tired now to continue...
regards hasan Test setup: - The serialized graph contains 148163 triples - The serialized graph is an n-triples file (each line is a triple) but parsed with a turtle parser - The serialized graph is parsed several times and in each time the result is always stored to the same mgraph replacing old contents A. With Jena-based Parser A1. Options used: -Xmx256m -XX:MaxPermSize=128M Parsing the first time results in: INFO Thread-26 org.apache.clerezza.platform.BootMonitor - The Apache Clerezza Platform is now operational.
