Hi everyone,
I am using Apache Jena Fuseki 4.6.1 to host 2 datasets (rdf + rdf-star).
I have noticed an unexpected behaviour on my server as my RAM gets filled
little by little over time ( 100 Mo / few minutes can be several Go at the end)
when no queries are received by the server. When I submit a query using fuseki
GUI the RAM gets freed (at least partially) from what seemed to have
accumulated into it in between queries.
The java process is using that memory see attached file. Note that I use the
standard configuration provided by the server except for the max memory that I
set to 20 Go. The java process is largely exceeding this limit as it may reach
over 50 Go.
Is it a known issue of Fuseki? Java?
Is there a way to monitor that better than just record memory use?
Any fix published or hint on how to solve that?
Best regards,
Christophe
