T Jake Luciani commented on CASSANDRA-12034:
--------------------------------------------
I think we should be careful here since this is adding a new kind of error for
users to think about.
How is this not a destabilizing condition? We don't know if it's this users
response or another that's taking up the memory, or when it will resolve.

> With CASSANDRA-12032, Netty throws a
> {{io.netty.util.internal.OutOfDirectMemoryError}} if there's not enough
> off-heap memory for the response buffer. We can easily handle this situation
> and return an error. This is not a condition that destabilizes the system and
> should therefore not passed to {{JVMStabilityInspector}}.
