Fuseki NullPointerException on 16 million triple dataset
Hello,
I am working on a mac os, fuseki apache-jena-fuseki-2.3.1
I increased the JVM size to:
JVM_ARGS=${JVM_ARGS:--Xmx6144M}
I have a database TDB without reasoner. I uploaded 16 million triples to it, when I query it, i got this error :

Could you help please ?

Ah, sorry I missed the other thread - I made the mistake of replying
while on a plane :)
I'll have a look if I am able to reproduce it, although I don't have a Mac.
Ania, which Java version do you use with Fuseki? (java -version)
BTW -
https://lists.apache.org/list.html?dev@jena.apache.org
looks pretty nice compared to the old archive :) -- also slightly shorter URIs.

Re: Fuseki NullPointerException on 16 million triple dataset
Posted by "Lorenz B." <bu...@informatik.uni-leipzig.de>.
She already made query and data available in another thread on the
mailing list.[1]
And Andy Seaborne could not reproduce the error with Fuseki 2.4.0

Re: Fuseki NullPointerException on 16 million triple dataset
Posted by Stian Soiland-Reyes <st...@apache.org>.
Hi,
What would help is if you could detail what kind of data (if it's public,
then we can try to load it as well) and what kind of queries you do.
Do you have a particular query that causes this stack trace?
Do you do multiple concurrent queries, or one at a time?

Re: Fuseki NullPointerException on 16 million triple dataset
Posted by Ania david <an...@outlook.com>.
Hi Andy,
How can I give you the whole data?
It is 2.5 GB, when the data is small, like 1GB, it is working good, but when I add the whole data, the query gives that error
I really appreciate if you can help me here since I've already finished (more or less) my Semantic App, but Fuseki now makes problem with big data size
