> It happens on all 6 nodes at the same time. Also we see increased client
> timeouts and dropped READ and READ_RESPONSE messages. Our Cassandra is
> 3.11.16, 2 DC setup, 6 node in each DC. RF is 3. I have searched issues but
> could not find exactly same issue causing messages to be dropped. Any
> suggestion would be appreciated.
