Hi Jason, Heap memory is not managed by Ignite, so such fluctuations are always possible. You can try to decrease heap size to 4g, for example, and check how it works. Depending on your use case this can be enough or not (but I would not recommend less).
As for off-heap, this can depend on different factors. Are your entries typically of the same size? Do you use any kind of collocation? Ignite affinity tries to evenly distribute entries across nodes, and if you simple put a lot of entries of the same size, consumed memory should be the same on all nodes. But in real use cases that's not always true. -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/How-is-memory-used-for-the-Ignite-server-node-tp6626p6632.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
