@YaphetKG @patrickkwang Any updates on this?

YaphetKG commented 4 years ago

Hi @Prakash2403 sorry for late reply, can you share the neo4j debug logs

Prakash2403 commented 4 years ago

Hi @YaphetKG , here are the logs related to uploading graph.9.9.19.dump.db.

Thanks for the help. Also, any updates on #491 ?

I think you might be having memory issues, it looks like you have run out of heap space, try bumping up the NEO4J_HEAP and NEO4J_INTIAL_HEAP and try loading it. The graph you are trying to load is big so that might be the issue

Okay, will try that
