If you think that will fix the problem, maybe you could add a little more
memory to each machine as a short term fix.

That warning isn’t sufficient to understand why the node is going down

Only one node having the problem is suspicious. May be that your application is

So your suggestion is to first resolve the data model issue which
cause wide partition,right?

Look for errors on your network interface. I think you have periodic errors in
