i hav done that what u say. but the OOM doesn’t appeared.
maybe that because of i expand memery and processor, i have doubled resource, and used -j 3 option, the memery use is below 22% at whole runtime.
and maybe there is another problem. seems like when there is many rdf file, if the resource defined in one file and other resource in other file has edge point to that resource, that edge will lost after bulk loaded…
i’ll try again
