Check added to ensure Job scheduler executed only once
Resolved in Pega Version 8.6.4
When Node A and Node B woke up at the same time to start executing the job scheduler, both were attempting to update the "now processing" node ID with their ID but only Node A succeeded. This caused Node B to generate a "lock already held" exception, then Node B would try to release the lock and update "now processing" node ID. If Node A released the lock before Node B tried to, then Node B updated the "now processing" nodeID and executed the scheduler, causing it to be run twice. This double-run has been resolved by adding a check for whether the job scheduler has been executed recently before starting it.

QueueProcessor timeout made configurable
Resolved in Pega Version 8.6.4
Queue Processor timeouts were causing thread interruptions, causing items to be processed more than once. To resolve this, the QueueProcessor kafka-write timeout has been made configurable via the DASS Pega-Engine:queueprocessor/dataset/write/timeoutMs

Scheduled-item operations performed in shared context
Resolved in Pega Version 8.6.4
Scheduled items were not getting processed either by DelayedItemsDataFlowService data flow or by reverting to the pzDelayedQueueProcessorSchedule Job Scheduler, and the number of scheduled items in the pr_sys_delayed_queue table continued to grow even though DelayedItemsDataFlowService showed the processed record count to be increasing. Because the Admin Studio portal was not equipped to show the scheduled record count for the tenant layer in a multi-tenant environment, only the scheduled record count for the shared layer was shown. This has been resolved by updating the system to perform scheduled-item operations in shared context.

Job Scheduler explicitly unlocked after nodes restart
Resolved in Pega Version 8.6.4
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.

Dashboard widget drilldown section adjusts dynamically
Resolved in Pega Version 8.6.4
While trying to expand the drilldown columns, text was overlapping due to the grid not adjusting the large size of data dynamically. This was traced to an unnecessary CSS rule being applied to set max-height which broke the styling. This has been resolved by removing the height limitation on detail cells.

Resolved in Pega Version 8.6.4
Selecting more than 20 values in the multiselect control caused the scrollbar to disappear. This has been resolved by removing a custom popover height calculation.

Corrected vertical scroll bar for iPad Mashup page
Resolved in Pega Version 8.6.4
After update, the vertical scroll bar shown on the Web Mashup page in Apple Safari on iPad continued to increase and showed excessive blank space. This was caused by the iframes,section height being considered as the iframe height, and has been resolved by setting the section height as 'auto' in case of mashups.
