Prediction outcome response timing updated
Resolved in Pega Version 8.7
Predictions using a response timeout were not emitting a negative response ('NoResponse') when the specified waiting time expired. This was traced to the the outcome and response timeout values being overridden while triggering responses for multi stage predictions along with chained predictions. This has been resolved by modifying the flow to emit each outcome as it is received and by adding the dataflow trigger in the function so that it does not override the values in case of chained predictions.

Tombstone cleanup modified to handle very large volume environments
Resolved in Pega Version 8.7
Cassandra nodes were periodically suffering from an out of memory condition. This was traced to tumbling windows creating too many tombstones for Cassandra to clean up effectively when running in a very high volume environment with a short tumbling time. This has been resolved by modifying the procedure away from using individual tombstones to instead use range tombstones which will continuously supersede the previous tombstone so there is never an opportunity for them to build up.

Performance improvements for action check-in
Resolved in Pega Version 8.7
The process of 'Saving As' an action to a higher ruleset, Saving, and then running Check-in was taking an excessive amount of time. This was traced to redundant page copy activities and performance has been improved by updating the implementation.

Performance improvements for stale thread warnings
Resolved in Pega Version 8.7
Stale thread warnings were causing performance issues during dataflow run execution. Stale thread/slow component warnings are added as part of the dataflow execution when a processing thread takes more than 5 minutes to process a single dataflow record. The stacktrace of the dataflow thread is added as part of the warning for debugging purposes, but in some scenarios the stacktrace can become very large. This has been resolved by removing the stacktraces from the warning, improving the query logic, and adding the run ID to the exception method to assist if there is an error.

Resolved OOM error when adding VDB DNode
Resolved in Pega Version 7.2.2
A memory leak was found relating to JBDC PreparedStatement objects (char arrays allocated to hold database query results) used when VBD loads its data partitions. This has been fixed with the addition of code to close the PreparedStatement objects created when loading Actuals partition data.

Added handling for Qualsys security scan
Resolved in Pega Version 7.2.2
A stack overflow error was being generated when running a Qualsys vulnerability security scan on servers hosting IBM WebSphere and Pega, resulting in two of the three Pega nodes in production becoming unresponsive and requiring a restart. This was caused by the third party tool connecting to port 7003, which is used by Stream data set server, and sending unknown requests. To avoid this, the system has been updated to not send back a response if the channel is closed

Corrected ability to add DNode port via prconfig
Resolved in Pega Version 7.2.2
Adding DNode Port via prconfig was not taking effect due to the configuration values being stored as strings, but the code which reads the storage port configuration treats the setting as integer. This has been fixed.

Dynamic setting added to override ADM JMS default
Resolved in Pega Version 7.2.2
ADM (a part of Pega DSM) was detecting JMS and switching over to JMS when available and using HttpInvoker in other cases. In order to allow customization, it is now possible to override the ADM JMS configuration and allow EAR deployments by way of a dynamic system setting to disable JMS at will.
