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).

Database primary keys generated as NONCLUSTERED for imports
Resolved in Pega Version 8.4.5
When a primary key was defined for a table and the table was exported and then imported, the primary key was generated as CLUSTERED. This resulted in an MS SQL Cluster Index violation because all Pega-shipped tables generated during installs/upgrades have a PK constraint index with NONCLUSTERED index type as it allows for a longer key. This was a missed use case, and has been resolved by updating the system such that when importing with MS SQL database, the primary key index is made NONCLUSTERED all the time so it will be consistent with the base platform.

Pega Catalog custom upload control modified
Resolved in Pega Version 8.4.5
Attempting to upload a catalog.zip file caused the system to hang and thread dumps were seen in the logs. Investigation traced the issue to the custom control used to upload the catalog, which was posting the entire content in form data rather than sending a multi-part request. The control contained both legacy code which used form.submit() and encoding along with new code that used SafeURL and sent an async request. With this, encoding could not be set to multi-part in case of an AJAX request. To resolve this, the catalog upload control has been modified to use the appropriate legacy code that performs form.submit() and sets the encoding properly.

Filter considers all instances pages during deployment
Resolved in Pega Version 8.4.5
During package deployment, attempting to use Filter to skip some of the instances only displayed the result of the current active page instead of all pages. This was an unintended consequence of previous work, and has been resolved by adding the logic to strip quotes in the value and adding the "Pagination activity manages filtering" checkbox by default.
