I agree. It took around 1 month for us to determine which client was causing
the problem.
With this change in this ticket, it will save time for many Cassandra users.

> We are getting hundreds of the below warnings in Cassandra logs:
> {code:java}
> WARN [epollEventLoopGroup-5-7] 2024-11-10 00:26:24,296
> ExceptionHandlers.java:139 - Unknown exception in client networking
> io.netty.channel.StacklessClosedChannelException: null
> at io.netty.channel.AbstractChannel.close(ChannelPromise)(Unknown
> Source)
> {code}
> This means the client dropped the connection abruptly or abnormally. The
> issue could be a network or application issue on the client side.
> Since there could be many client servers, Cassandra must log the client IP
> and the port so we can check what's the problem with that server.
> I'll attached the fix for this small change.
