Hello Ray, Can you please share your Ignite configuration? That including persistence settings and cache configuration and memory policy.
Does it get stuck for good, or does it get un-stuck periodically to do some loading? This might be related to checkpointing. Try setting PersistentStoreConfiguration's checkpointingFrequency to 600000 and checkpointingPageBufferSize to at least "#{8L * 1024 * 1024 * 1024}" (while making sure that onheap + offheap + checkpointing buffer + and then some < total available memory.
