Stale Cluster Node Cleanup Property

Products

• CA API Gateway

Issue/Introduction

We have set the com.l7tech.server.clusterStaleNodeCleanupTimeoutSeconds setting within the system,properties file to a value of 600 but notice that stale gateway nodes are getting removed from the cluster_info table well after this time frame.

Environment

All supported versions of the CA API Gateway

Cause

There is an internal scheduled task which will run every hour to remove stale gateway nodes from the cluster_info table based on the com.l7tech.server.clusterStaleNodeCleanupTimeoutSeconds value.

Resolution

As the internal task runs once per hour or 3600 seconds you should look to set the com.l7tech.server.clusterStaleNodeCleanupTimeoutSeconds setting to a higher and more appropriate value.
