Web Tier busy threads released on timeout
Resolved in Pega Version 8.6.1
Tomcat Web Tier Busy Threads were not being correctly released, causing stability and performance problems that included health check pings not receiving a thread to service the request so the node was marked as bad, users were quiesced, and the node replaced. Investigation showed the 'put' on the blocking queue did not time out when the queue was full and waited indefinitely, keeping the thread blocked. To resolve this, the system will use 'offer' on the blocking queue instead of 'put' to force thread release on timeout. In addition, debug logs have been added to understand when the offer (or Put) does not succeed and the state of the queue that is causing this issue; the debug logs for class com.pega.pegarules.session.internal.serverpush.RoboticAutomationImpl should be enabled only if the thread busy issue is observed and for limited time window while actively debugging.

Resolved Push Node Daily Information exception
Resolved in Pega Version 8.6.1
The "Push Nodes Info Daily" agent was generating an exception on each of the nodes. This has been resolved by enhancing the PegaAESRemote code to handle the exception and get the node info locally, then push it to the console when it is not able to get it via the cluster management API.

Certificate match will use Subject Distinguished Name
Resolved in Pega Version 8.6.1
Signature verification was failing due to the system not finding the matching root certificate for the chain. The root certificate was in the trust store, but the system found a different certificate first and that other certificate (an intermediate certificate) was not considered a valid certificate for validating the whole certificate chain. This was traced to filtering on the Issuer Distinguished Name (DN) instead of the Subject DN and was due to intermediate certificates potentially having the same Issuer as a root certificate (e.g. if that root certificate was used to create the intermediate certificate). To resolve this, an update has been made to check the Subject DN instead of Issuer DN.

Instance count logic updated
Resolved in Pega Version 8.6.1
A performance issue was seen during update that resembled an upgrade hang. This was caused by a combination of incorrect logic in DDLGenerator.getInstanceCountForClass() around counting instances of 'core' classes and all of the site history-data- tables being mapped to the same table that had 1.4+ billion rows. This behavior has been addressed with more correct query logic while performing instance counts. In addition, instance count will be supressed during command line invocations (prpcUtils, platform upgrade).

Installer files updated with class loader conflict resolution assistance
Resolved in Pega Version 8.2.4
When sending emails with attachments, errors were observed relating to a loader constraint violation indicating that when resolving interface method, the class loader of the current class and the class loader for the method's defining class had different Class objects for the type used in the signature. The resolution for this requires user configuration of the app server, and the following files for the install guide have been updated with the appropriate information:Deployment-guides-dita/install.ditamap Deployment-guides-dita/Content/Topics/app-server-config/creating-jdbc-driver-module-jboss-tsk.dita Deployment-guides-dita/Content/Topics/app-server-config/delegating-javax-activation-to-JRE-loader-tsk.dita

Added timeout handling for non-PRAuth servlets
Resolved in Pega Version 8.2.4
After logging in via external authentication service (SAML Single Sign On) and setting up a timeout in the access group RuleForm, when the user performed any action and the server identified the request to be timed-out, it was expected that a SAML request would be sent from the browser to the external Authentication Server (referred as IDP) and the flow would proceed from there. This worked as expected for a non-AJAX request. To resolve this, handling has been added for timeout when using non-PRAuth authentication services.

SAML data pages restored after passivation
Resolved in Pega Version 8.2.4
If login used SAML SSO, resuming the session after passivation resulted in missing or empty data pages when using an SAP integration with Pega Cloud. This was traced to a security change that modified the D_SAMLAssertionDataPage and D_SamlSsoLoginInfo data pages as readonly, causing them to not be passivated under these conditions. To resolve this, the data pages have been made editable so they will be restored as expected. This change also resolves any difficulty with SAML logoff activities in conjunction with SAP and Pega Cloud.

prproductmigration build.gradle updated for new mime4j asset name
Resolved in Pega Version 8.2.4
While running the getMigrationLog for ProductMigration script provided in the Pega 8.2.2 media files, errors appeared referencing "NoClassDefFoundErrors when running getLogs". This was caused by the referenced class not being found on the classpath: the version of the included jar did not include the class needed due to Praxiom's default version being updated to use a new version of mime4j that required an asset name change. To resolve this, the mime4j asset name in prproductmigration build.gradle has been updated to pick up the correct version of the dependency for Praxiom.
