Hi Ben,
Thanks for your reply, we tested the same workload on kernel
version 4.6.4-1.el7.elrepo.x86_64 and found the issue to be not present
there.
This had resulted in really high CPU in write workloads -> area in which
cassandra excels. Degrading performance by atleast 5x! I suggest this
Hi Abhishek
The article with the futex bug description lists the solution, which is to
upgrade to a version of RHEL or CentOS that have the specified patch.
What help do you specifically need? If you need help upgrading the OS I
would look at the documentation for RHEL or CentOS.

Hi,
We are seeing an issue where the system CPU is shooting off to a figure or
> 90% when the cluster is subjected to a relatively high write workload i.e
4k wreq/secs.
