Thank you, it's an Out of memory crash according to dmesg. I have the heap size set to 15G in the jvm.options for cassandra, and there is 30G on the machine.

Have a look at dmesg. It have already happened to me regarding type i instances at AWS.

I had 2 nodes go down today, here is the ERRORs from the system log on both nodes
For some context, I'm trying to get regular repairs going but am having issues with it.

Can you grep ERROR system.log

There is nothing in the system log about it being drained or shutdown, I'm not sure how else it would be pre-empted. No one else on the team is on the servers and I haven't been shutting them down. There also is no java memory dump on the server either. It appears that the process just died.

What do you mean by "no obvious error in the logs", do you see node was drained or shutdown. Are you sure, no other process is calling nodetool drain or shutdown, OR pre-empting cassandra process?

I have a 6 node cassandra cluster running, and frequently a node will go down with no obvious error in the logs. This is starting to happen quite often, almost daily now. Any suggestions on how to track down what is causing the node to stop? --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscribe@cassandra.apache.org For additional commands, e-mail: user-h...@cassandra.apache.org
