[~george0st] do you see any server side logs related to that by any chance? 
Turn on debug / trace logging etc.

>             Project: Cassandra

>            Reporter: jist
>            Priority: Normal

> I got these errors during performance tests:
>  * NoHostAvailable: ('Unable to connect to any servers', 
> {'10.129.53.159:9042': ConnectionShutdown('{*}CRC mismatch on header 22f840. 
> Received 85\", computed e3d12c.{*}')})
>  * NoHostAvailable: ('Unable to connect to any servers', 
> {'10.129.53.159:9042': ConnectionShutdown('{*}CRC mismatch on header 718a02. 
> Received 85a8\", computed a7811f.{*}')})
> I used this connection setting with {{ProtocolVersion.V5}} :
> {code:java}
> self._cluster = Cluster(contact_points = self._run_setup['ip'],
>             port = self._run_setup['port'], 
>             auth_provider = auth_provider,
>             load_balancing_policy = load_balancing_policy, 
>             control_connection_timeout = Setting.TIMEOUT, 
>             idle_heartbeat_interval = Setting.TIMEOUT,
>             connect_timeout = Setting.TIMEOUT, 
>             protocol_version = ProtocolVersion.V5){code}
> I did not get the mistake about CRC mismatch, when I used 
> {{{}ProtocolVersion.V4{}}}. It seems on the first view, that 
> {{ProtocolVersion.V5}} generates these issues.
> BTW: I am probably able to simulate the issue repeatable in case of request 
> (I got these issues in Cassandra version 5.0.0)
