Locking issue resolved for passivating requestor
Resolved in Pega Version 8.4.6
A null pointer error was seen when passivating a requestor related to AbstractPassivationStorage.deleteAssociatedRequestorContents. This was traced to the lock to being called on the app requestor and not properly released. This has been resolved by ensuring the lock will be cleared when the Requestor is destroyed/returned.

Service Email handling updated for MSGraph "From" address
Resolved in Pega Version 8.4.6
While creating cases via email listener, the "From" address was not shown when using MSGraph. This was an issue with extracting the display name when MSGraph is used, and has been resolved by adding double quotes to display the name unconditionally.

Check added to ensure read locks are released
Resolved in Pega Version 8.4.6
Read locks were not being properly released if a thread was holding a read lock and the system encountered an issue such as an out of memory condition. To resolve this, an update has been made to DeclarativePageDefinitionCacheImpl which will check whether a thread holds any read lock before trying to acquire a write lock, and if so release all the read locks held by that thread.

Cleanup added for disabled/deleted operator passivation data

ServicePackage thread handling improvements
Resolved in Pega Version 8.4.6
Work recently done to improve the release of requestor pool threads for the ServicePackage has been further enhanced by adding an explicit status notification to the thread waiting for Data Pages to be loaded in background and added support for the use case of a missing object handler. This also resolves a 504 Gateway Time-out error intermittently seen while trying to open the URL of the Pega application.

Documentation updated for using Connect MQ with clustered queues
Resolved in Pega Version 8.6.3
After update to Pega Platform v8.6, an issue was seen with Connect MQ rules that used an alias queue. The support documentation has been revised to outline the necessary steps for updating an application to perform as expected. In the Pega-IntegrationEngine ruleset, create the following dynamic system settings and their default values: "mq/pmo" = 0 "mq/gmo" = 0 "mq/oo_request" = 1040 "mq/oo_response" = 16 For more information, dynamic system setting support articles are available.

Handling updated for queue processor locks
Resolved in Pega Version 8.6.3
The Final activity mentioned in the processing epilog of the Service File rule was not being consistently called from File Listener, causing some of the cases to become stuck and not continue to the next stage. Investigation showed that if the lock was held by the queue processor requestor, the system was unable to obtain the lock but still proceeded to update the LogServiceFile page and persist it. This resulted in overwriting changes made on the LogServiceFile page by the requestor, resetting the completed-batches-count set back to 0. To resolve this, RuleServiceFile -> updateLSFBatchCounts() will call the overloaded lockAndLoad() method in LogServiceFile that accepts a parameter called lockAttempts. This will attempt to obtain a lock for a given number of times before throwing an exception.
