Agent restart made more resilient
Resolved in Pega Version 8.5.4
During a timeout outage, agents intermittently encountered a NoClassDefFound error and were disabled. After the database connection was restored, the agents were not automatically restarting. This has been resolved by making the code more resilient to errors; agent will be restarted when a temporary issue is detected, and the restart will be immune to most exceptions.

ServicePackage threads properly released
Resolved in Pega Version 8.5.4
After completing a system stress test, the requestor pool threads for the ServicePackage were not released. Investigation showed that the threads were waiting for Data Pages to be loaded in the background even though there was no background job corresponding to those data pages in the Async Services pool. This has been resolved by making an update to avoid removing the object handlers when the load-datapage finds that an entry exists with a NOT_STARTED state.

Timeout for node to join cluster increased and made configurable
Resolved in Pega Version 8.5.1
Hazelcast timeouts were causing application restart failures. This was traced to a rare case scenario of heavy processing on the primary node causing the new node to not be able to join the cluster within the designated 5 minute threshold. To compensate for this, the default time to join has been increased to 9 minutes and a prconfig setting has been added to configure the time setting.

Automatic agent restart added for temporary connection issues
Resolved in Pega Version 8.5.1
An agent that was stopped due to an issue with the database connection did not recover when the connection was reestablished. To resolve this, updates have been made that will handle an automatic restart of the agents when there are temporary connection issues.

Modified thread data page cleanup
Resolved in Pega Version 8.5.1
Some cases were becoming stuck at a particular stage and not proceeding further even though the task in the backend was complete. Investigation traced this to work done that removed declarative pages at the thread level to optimize performance while other clipboard pages were retained, and the issue has been resolved by deleting all thread data pages after every item processed by the agent.
