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.
