Cassandra - 100% CPU usage

Kong 0.15
Cassandra 3.11

For an undefined reason, on almost any request (with authentication plugin enable - oauth2/key-auth) Cassandra CPU usage grow to 100%
Any recommendations/tools about debugging Cassandra?
I didn’t find in logs any info related to this behavior.

Check gc.log . Sounds like a mistuned jvm.

$ grep start gc.log.0.current | tail

Start I guess will be keyword

We found that enabling authentication between kong and Cassandra (CQL username/password) it one of the main cause of this behaviour
