Products

• CA API Gateway

Issue/Introduction

After upgrading/migrated the Appliance Gateway from 10.1CR04 to 11.0CR02, the following new WARNING message is seen in the logs:

WARNING 1 com.hazelcast.cp.CPSubsystem: [xxx.xxx.xxx.xxx]:8777 [gateway] [5.2.1] CP Subsystem is not enabled. CP data structures will operate in UNSAFE mode! Please note that UNSAFE mode will not provide strong consistency guarantees.

Environment

API Gateway 11.x

Resolution

We do not use the CP subsystem for the internal Hazelcast. To be able to enable it, you need a minimum of 3 nodes for a dedicated external Hazelcast but is not available for the internal one.

This message can be safely ignored. Some more info can be found at: https://docs.hazelcast.com/imdg/4.2/cp-subsystem/unsafe-mode
