"Region /_ConfigurationRegion has potentially stale data. It is waiting for another member to recover the latest data." log message when restarting locators in GemFire cluster

Issue/Introduction

Cluster config directory on locators is similar to the disk-store on cache servers in GemFire. In other words, the cluster_config directory on locators behaves similarly to the data directories on servers.

When enable-cluster-configuration=true, then the GemFire cluster configuration service persists the cluster configuration created by gfsh commands to the locators in a cluster and distributes the configuration to the members of the cluster.

While restarting the locators, you may see the following log message:

Region /_ConfigurationRegion has potentially stale data. It is waiting for another member to recover the latest data.

Resolution

To avoid this log message when restarting the locators, start all locators parallel or in the opposite order of stopping the locators.
