Jeremy Hanna commented on CASSANDRA-8969:
-----------------------------------------

Any more thoughts on this change to make sure people don't unwittingly cause 
heap problems by setting the timeout extremely high?

> Add indication in cassandra.yaml that rpc timeouts going too high will cause 
> memory build up

> It would be helpful to communicate that setting the rpc timeouts too high may 
> cause memory problems on the server as it can become overloaded and has to 
> retain the in flight requests in memory.  I'll get this done but just adding 
> the ticket as a placeholder for memory.
