Last updated on FEBRUARY 24, 2017

Applies to:

Oracle Coherence - Version 3.7.1 and later
Information in this document applies to any platform.

Symptoms

In a Coherence Cluster some of the nodes are using much more CPU than expected (around 30%) even on idle periods when the cluster is almost not accessed. A JFR output analysis shows the Invocation:Management thread is using most of the CPU.
