Service Registry heartbeat updates
Resolved in Pega Version 8.4.2
If a service (node) did not update its heartbeat for more than 90 seconds, eventually these stale services were removed from the database because the service registry did not consider them present. To resolve this, topology listeners will now use a java thread pool to run their logic and no longer use the heartbeat thread. Even if these listeners are slow, it won't affect the heartbeat and won't cause nodes to become unhealthy. If for some reason the heartbeat becomes slow (due to database issues) it will issue a thread dump to help identify what causes the slowness and aid in troubleshooting.

Unneeded MBean startup warning removed
Resolved in Pega Version 8.4.2
After upgrade, Catalina logs indicated the error "WARN com.pega.dsm.dnode.api.prpc.service.monitoring.MBeanDSMService - Service DataFlow doesn't implement Monitoring operation". This was due to a flaw in the way the data flow DSM service was initialized in client mode. The exception itself was not a problem and did not impact functionality, but the client initialization has been modified to remove the warning.

Improved timing for node tracing termination
Resolved in Pega Version 8.4.2
The tracer stopped tracing after tracing a certain number of events. This was due to communication timing issues for tracer events from one node to another node in a multi-node cluster environment, caused by the Tracer Client using the pzMaxEvent property which limited the maximum number of events fetched at a time to 200. Any leftover Events should have been fetched in the next request, but when the consuming node's service ended after the 200 events, the system removed the service requester entry from the distributed Map and disabled remote node tracing as part of cleanup of the service execution. To resolve this, an update has been made so the node tracing will not be terminated until the service execution ends and there are no more events to process.

SAML SSO redirects to correct URL when application and authentication aliases match
Resolved in Pega Version 8.5.3
Whenever there was a match in the authentication service alias and the application alias, the application alias was replaced with empty after logoff instead of making the authentication service alias empty. For example, given an authentication service with the alias XYZ ("login with XYZ" alias option) and an application name XYZMyOps, the application alias was being changed from XYZMyOps to appMyOps after logoff. As a result, a blue screen error resulted when clicking on button "login with XYZ" again because it redirected to appMyOps, which didn't exist. This has been resolved by removing authservicealias and modifying AuthServiceAliasHelper.adjustPathIfAuthServiceAliasPresent() to change the method for calculating the pathinfo to string tokenizing
