Micah Green did you apply any tuning parameters also to RHEL apart from the
solution provided. As I can see some nodes swapping still.

We have been experiencing swap issues on rhel 8.7.4 across 1000s of nodes.
https://access.redhat.com/solutions/6785021. This is obtrusive enough that
our linux engineering team decided to push a patch through to all of our
teams. Once we updated the appropriate setting per the link I shared, all
Thanks Tibor. I know that swapping should be disabled, that is a general
recommendation.
I wanted to know i*f anyone using Cassandra on RHEL faced any issue while
moving from Rhel 7.x to Rhel 8.x. *

That doesn’t sound like a RHEL issue. Swapping can severely impact performance,
that’s why it is recommended to turn off swap on Cassandra nodes. This was
recommended in the Cassandra documentation by DataStax[1]. Apache Cassandra is
testing that and log a warning on startup [2] if swap is found
Has anybody seen issues running Cassandra on RHEL 8.6. I am seeing
