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).

Global obfuscation key initialized on first requestor call
Resolved in Pega Version 8.6.4
When using URLEncryption = true and SubmitObfuscatedURL = optional, attempting to export an Excel spreadsheet resulted in the error "Invalid character found in the request target". This was traced to the variable pega.d.globalobfuscateKey having a null value which was then converted to a byte array and decoded, generating improper characters in the URL. After a browser refresh, the correct value was set in pega.d.globalobfuscateKey and the export worked as expected. To resolve this, an update has been made to initialize the key on the very first call in PRRequestorImpl when the global obfuscation key is determined to be NULL instead of initializing the global obfuscation key by on-demand basis from HTTPAPI.

Added security tokens to Worklist assignment error wizard
Resolved in Pega Version 8.6.4
After enabling CSRF, moving to 'Configure -> Case Management -> Tools -> Work Admin -> Worklist assignment errors' and then selecting a record and clicking on 'Delete' resulted in a '403 Forbidden' error. This has been resolved by adding CSRF and fingerprint tokens as part of the form data.
