Restored local blocking queue cache
Resolved in Pega Version 8.6.3
After update, it was not possible to bring up secondary VBD nodes after restarting. Investigation traced this to earlier work done to resolve a memory leak issue, in which stale entries for local blocking queues were removed from cache. This resulted in modifying the queue listener logic to use "cache.getQueueIfPresent(jobId)" instead of "cache.getQueue(jobId)". Because the listener was not creating the cache if it was not present and the cache which held the local blocking queue didn't have the entry for the current remote execution job ID, the caller of the remote execution on Node2 ended up in blocking state forever, waiting on the local blocking queue. To resolve this, the code has been updated to ensure the blocking queue is created and stored in the local queue cache before publishing the remote job message.

Catch added for missing DelayedItemsDataFlowService run options
Resolved in Pega Version 8.6.3
The exception "Caused by: java.lang.IllegalStateException: Loaded a work object [DelayedItemsDataFlowService] while no run config was present" was logged while initializing the DelayedItemsDataFlowService, causing a shutdown. Investigation showed this was caused by corrupted data in the database post update, where the database was missing a row in pr_data_decision_ddf_run_opts representing the run options of 'DelayedItemsDataFlowService' while the work object record was present in the database. To resolve this, an update has been made to catch exceptions generated by DataFlowService and report them as logs and alert. This will prevent the startup task from failing and stopping the process.
