Enabled turning off general metrics when queue processing metrics are disabled
Resolved in Pega Version 8.8
A memory leak related to QPGeneralMetrics was consuming heap and causing performance issues. Investigation showed queue processor metrics were gathered even when disabled. To resolve this, turning off "General Metrics Handler" while turning off the QPGeneralMetrics has been enabled. Queue processors should now skip the process of collecting general metrics while running activities. This will prevent storing unused (and uncleared) metrics in memory and prevent heap exhaustion.

Improved handling for thread resolution issues
Resolved in Pega Version 8.8
Queue Processor/Dataflow was moving to STOPPED state due to failed records in its execution. Investigation showed there was a minor logic issue in the queue processor activity which allowed the Page-Remove step to be called even before the pages were actually created, and this has been resolved by improving the recovery from a cleared ThreadContainer which might cause thread resolution issues.

Override added to delete records for a stream dataset after processing
Resolved in Pega Version 8.8
Kafka data was accumulating for a Stream data set due to huge volume of inbound calls. This has been resolved by adding support to override pyDeletedProcessed through a DASS in order to remove the records for a particular stream dataset (topic) as soon as they are processed by Pega.

Service SOAP outflow response supports RSA_SHA256 & RSA_SHA384
Resolved in Pega Version 8.8
When service SOAP was configured in Pega WS-Security Profile with with outflow as signature and the signature method selected as RSA_SHA256, the response from service SOAP was still RSA_SHA_1 and the digest method was SHA_256. This has been resolved by updating WS-Security Profile to support RSA_SHA256 & RSA_SHA384 in service SOAP outflow response.

Job Scheduler explicitly unlocked after nodes restart
Resolved in Pega Version 8.8
If a job scheduler was in running state and the utility nodes were restarted, the background processing nodes were not coming up and resuming as expected and PersistentJobCleanupFactory:PresentMembersJobCleanup was throwing a stale execution exception. Investigation showed locks were not being removed from the database for the job scheduler when the restart was performed (noted in pegadata.pr_sys_locks table), preventing further runs. This has been resolved by adding an explicit lock removal process for this condition.

Clipboard page instance resolution simplified
Resolved in Pega Version 8.8
Previous work related to removing duplicate clipboard page creation from the pyInstanceInfoForUpdate list in order to resolve out of memory issues has been further updated to address a missed use case. While finding a matching instance with same className during instance list resolution, fault logic was leading to the same java object instance being updated N times and added N times to a linked list. This caused unnecessary complexity and has been resolved by removing the matching instance logic and instead creating items for each entry individually.

An exception was appearing as part of Robotic Desktop Automation (RDA) flow whenever message service host was not configured. This has been resolved by skipping the connection list API call when the message service host is not configured. A specific Pega log and console log messages have also been added.
