Old Tumbling Time data in event strategies given TTL for cleanup
Resolved in Pega Version 8.4.1
Old Tumbling Time data keys in event strategies were not being cleaned up, causing Cassandra timeouts after the dataflow run had been running for several months. The longer the dataflow was running using standard compaction, the more the data was potentially spread out across SSTables and the slower it became. This has been resolved by adding a 'time to live' value for tumbling time windows, and event strategies has been switched to use leveled compaction by default.

Upgraded Apache UIMA Ruta libraries to resolve memory leak
Resolved in Pega Version 8.7
A memory leak issue that resulted in a reboot being needed every few days was traced to the class org.apache.uima.ruta.rule.RuleMatch. This has been resolved by upgrading the Apache UIMA Ruta libraries to v2.8.1.

DateTime validation works correctly after importing invalid data
Resolved in Pega Version 8.7
After creating DecisionData (Dev studio) and adding a DateTime property to the form, importing records with invalid DateTime values failed with a validation error on the screen and the message "Error while converting format for data type DateTime property name Test_date_format with value scvf" was logged. Attempting to proceed by correcting the DateTime property and uploading worked, but any subsequent imports in the same session silently allowed invalid inputs to be passed without any validation errors and then showed blank date fields. This has been corrected.

VBD data flow timeout increased and made configurable
Resolved in Pega Version 8.7
Intermittent VBD timeouts were seen when writing records to MSK even though no errors were reported on the MSK side. Analysis showed that while batch data flows retry when a timeout occurs, real time data flows do not retry and the configuration to wait up to 10 seconds for an acknowledgement may not be sufficient depending on the system conditions. This has been resolved by increasing the default timeout to 20 seconds and adding a configurable timeout "vbd/streamPublishTimeoutMillis" to allow a customized setting.

ADM Models correctly updated
Resolved in Pega Version 8.7
The ADM models were not being updated when responses were processed either via the CaptureResponse API or when the time elapsed that should result in an update reflecting a non-response. This was traced to incomplete handling for a response coming for some other model which was converted to EMPTY, and has been resolved by modifying the logic so that the default responses and other responses are processed properly.

Hazelcast remote execution not called from synchronized context
Resolved in Pega Version 8.7
After navigating to the Admin Studio portal to view the nodes, the portal was temporarily freezing. Investigation of the thread dump revealed this was caused by a DDS pulse sending a remote execution call to all nodes to update logger settings even though the site was not using DDS. This has been resolved by updating the system to avoid calling Hazelcast remote execution from a synchronized context.

Updated ConfirmHarness handling for case type creation
Resolved in Pega Version 8.7
If a new case type was created with the initialization stage and there were no assignments in the case type, the /cases API did not return a NextPageID in response. This has been resolved by setting the pyConfirmHarness parameter before calling addworkobject.
