Service Registry does not consider node if hearbeat not updated

KCP-478

Summary



The Service Registry does not consider a Service node, if the node has not updated its heartbeat for more than 90 seconds. However, these stale services are removed from the database later. If the heartbeat takes longer than its beat to update services, then the hearbeat must display a thread dump at that moment to determine where it has stopped.


Error Messages



Not Applicable


Steps to Reproduce



Not Applicable 


Root Cause



A defect in Pegasystems’ code or rules.
Some platform components do not use the Service Registry API correctly, causing the heartbeat to slow down. As a result, the node becomes unhealthy.


Resolution



This feature is implemented in Pega Platform 8.3.4.
