Web Tier busy threads released on timeout
Resolved in Pega Version 8.5.4
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 8.5.4
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 8.5.4
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 8.5.4
A performance issue was seen during upgrade 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).

Added exception handling for PageGroup alerts
Resolved in Pega Version 8.6.5
Queue items were going to the broken queue if there was an issue fetching the alert configuration from the Queue Processor rule. The error "java.lang.IllegalArgumentException: Alert id cannot be blank" was seen. This has been resolved by adding exception handling while gathering alerts from PageGroup so that a malformed alert configuration will not cause overall failure of a processed message, but instead an empty alert will be returned if configuration-data is corrupted.

JobScheduler updated to better handle DST change
Resolved in Pega Version 8.6.5
If a job scheduler was set to run on a weekly basis between 1 AM CET and 3 AM CET, the DST time change caused the job scheduler to skip that week. During DST, there is one 23-hour day in the year, and if execution time is set to that missing hour the system was throwing an IllegalArgumentException for the non-existent date. This has been resolved by adding a check that verifies whether a given date does exist; if it does not exist, the system will postpone execution time by one hour.

Error text revised for parameterized data page used for token generation
Resolved in Pega Version 8.6.5
While trying to add a claim in the header of a Token Generation Profile instance, selecting Map From as "Clipboard" and trying to give any DataPage(parameterized) as the source property failed to be saved and the error "JWS Alias— Please provide correct algorithm key with correct key length." appeared. Changing the "Map From" to a Constant and giving a dummy value worked as expected. Tracer showed the error "declare page parameters not supported by PropertyReference", indicating the actual issue: at this time, the Token profile does not support using a parameterized data page. This has been addressed by ensuring an appropriate error message is shown on save of the token profile rule form when a parameterized data page reference is configured. The error will now read "The reference D_pzPreferenceStore[PreferenceOperatorID:"[email protected]"].pxObjClass is not valid. Reason: Parameterized data page reference is not supported." Support for a parameterized data page used with Map From will be taken as an enhancement for a future release.

Override added to delete records for a stream dataset after processing
Resolved in Pega Version 8.6.5
Kafka data was accumulating for a Stream data set due to huge volume of inbound calls. This has been resolved by adding support to override pyDeletedProcessed through a DASS in order to remove the records for a particular stream dataset (topic) as soon as they are processed by Pega.
