Column population honors thread count of 1
Resolved in Pega Version 8.2.5
The thread count parameter in the column population activity was not being honored, causing repeated deadlocks when trying to populate columns. Investigation showed that the ExposeCols process did not honor the thread count when it was 1 (the default is 4), and this has been fixed by adding the necessary code so that if the thread count is 1, it will not run in multhreaded mode.

Expired Oauth Refresh Token will persist for obtaining new token
Resolved in Pega Version 8.2.5
OAuth2.0 was providing the refresh token only once in the first time response of the token endpoint. Once the token expired for first time, it was possible to get a new access token using the refresh token. However, if the access token expired for the second time, it was not possible to generate the new access token automatically because the expired token was set as null. To resolve this, the system has been updated to persist the previous refresh token in order to get a new access token.

Modified timestamp query used by ClusterAndDBCleaner
Resolved in Pega Version 8.7.3
The job pyClusterAndDBCleaner was failing with the error "ORA-01861: literal does not match format string". This was traced to the sub-activity pzClearOldQueueProcessorBrokenMessages which was not able to remove broken items with encryption in an upgraded environment due to an incorrect timestamp format passed to the Oracle database. This has been resolved by modifying the query to use a timestamp built using INativeSqlBuilder which will include only the information necessary for the deletion of the item.

Enabled turning off general metrics when queue processing metrics are disabled
Resolved in Pega Version 8.7.3
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 8.7.3
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.
