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).

Updated dedicated index reindexing check
Resolved in Pega Version 8.7.1
Attempts to reindex were not successful after a dedicated index failed with the error "Not enough active shards for index work to meet write consistency of quorum". This has been resolved by updating the system to validate the cluster state for the dedicated index name instead of the work index name when performing a dedicated index Reindex.

Check added for child join class when using ABAC
Resolved in Pega Version 8.7.1
When a join was applied on a report definition and the same join class had a child class to which ABAC was applied (for some property eg., isABC), an "invalidreference" exception (isABC) was generated. This was traced to the system taking into account the child class of the join class while running the report, and has been resolved by adding a check to handle this scenario.

DSS added to control BIX extraction time properties
Resolved in Pega Version 8.7.1
After upgrade from Pega 7.3 to Pega 8, downstream systems were failing to process the BIX extract manifest summary file. This was due to three columns which were introduced in Pega 7.3.1 to handle any failures during BIX incremental extraction: pxStartCommitDateTime, pxEndCommitDateTime, and pxLastSuccessFulCommitDateTime. To support better backwards compatibility, this fix introduces the below DSS to allow disabling of the new columns.

Added handling for client-side validation errors in sub-reports
Resolved in Pega Version 8.7.1
When a sub-report was trying to access externally mapped fields or an optimized page property by JOIN of another class, the main report was unable to validate the Page property. This has been resolved by updating the activity code to handle client-side validation errors on main reports attempting to access the externally-mapped Page properties of another class in the sub-report.
