Ah, I had not thought of that, thanks. Interestingly, going to a smaller cluster seems to have worked around the problem. We were running a 44-node cluster using 3 backups of the data. Switching to two separate 22-node clusters, each with 1 backup, seems to work just fine. Is there some limit to how large a cluster should be?
@smovva - We were using c4.4xl instances, but switched to r4.2xl because we had spare CPU but kept having memory problems. I suspect that there isn't a "right" size to use, it just depends on the use case you have. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
