Thanks for your suggestion
we set MaxDirectMemorySize to 8g,it still has exception.
we use spark to read ignite.and use ThinIgniteClientOnK8s api to read.
we find that if multiple spark applications read ignite, then ignite will
hit the direct buffer memory oom.
can you give me some suggestions about how can i confirm that it is a
network problem?
Best Regards.
