Web Tier busy threads released on timeout
Resolved in Pega Version 8.5.4
Tomcat Web Tier Busy Threads were not being correctly released, causing stability and performance problems that included health check pings not receiving a thread to service the request so the node was marked as bad, users were quiesced, and the node replaced. Investigation showed the 'put' on the blocking queue did not time out when the queue was full and waited indefinitely, keeping the thread blocked. To resolve this, the system will use 'offer' on the blocking queue instead of 'put' to force thread release on timeout. In addition, debug logs have been added to understand when the offer (or Put) does not succeed and the state of the queue that is causing this issue; the debug logs for class com.pega.pegarules.session.internal.serverpush.RoboticAutomationImpl should be enabled only if the thread busy issue is observed and for limited time window while actively debugging.

Attach Documents Control updated for busy indicator timing
Resolved in Pega Version 8.4.4
When using the standard control - Attach content - to attach documents for processing in the application, selecting multiple files for upload and then clicking on the attach button before the busy indicator started resulted in not all files being uploaded. Investigation showed that the busy indicator was not set to display as soon as the attachments were added, giving an opportunity to click "Attach" before all the documents could be successfully added to the process. As part of the resolution for this issue, the busy indicator will be displayed immediately upon file selection.

Resolved startup error related to business calendar object
Resolved in Pega Version 8.5.5
An error recorded in the log file when the server started was traced to a cache update that removed the old business calendar object and added the new business calendar object to the business cal list. This has been resolved by updating the system to replace the business calendar object instead of removing the old one from the cache first.

Busy indicator correctly resolves with Microsoft Internet Explorer upload
Resolved in Pega Version 8.5.4
When using Microsoft Internet Explorer to upload documents, the busy indicator was not resolving after the file was attached. This was due to a missed use case in work done around the timing of the busy indicator when attaching multiple files, and has been resolved by modifying PzMultiFilePath to ensure the busy Indicator is removed when the file count is zero.

Out of memory condition resolved for BIX extraction
Resolved in Pega Version 8.5.4
A node was going down automatically during execution of a BIX Extract rule when working with old objects. Investigation showed this was related to an out of memory error: the work object had nested page lists, and when one of the page lists contained a propertylist which contained more records, the system was trying to add entries to the LinkedList if any properties were missing the reference during extraction. Because LinkedList allowed duplicates, it filled with enough errors to cause the out of memory condition. To resolve this, LinkedList has been replaced with LinkedHasSet, which does not allow duplicates.

Business users can move dashboard widgets on production portal pages
Resolved in Pega Version 8.5.4
Business users were not able to use "Edit dashboard" to move dashboard widgets in production portal pages. This was a missed use case of using an operator with different security level, and has been resolved by using the control pzUserDashboardIncludeScript instead of including pzpega_dashboard script directly in the UserPortal harness.

Handling added for large BIX Postgres data sets
Resolved in Pega Version 8.6.5
BIX extracts were causing timeouts or JVM out of memory errors. This was traced to the Postgres JDBC driver ignoring fetch size in auto-commit transaction mode, which led to everything being loaded into memory at once. To resolve this, changes have been added to support fetch size for large results when using PostgreSQL database for BIX Extraction.

Handling added BIX extraction failure when called from custom activity
Resolved in Pega Version 8.6.5
After update, BIX extraction was failing but email from the schedulers indicated success. Investigation showed that when extract was called from a custom activity by calling pxExtractDataWithArgs, the stepStatusFail 'when' rule in the custom activity was not capturing all the exceptions specific to database extracts. This has been resolved by adding the necessary handling.

Decision table query performance improvements
Resolved in Pega Version 8.5.4
Severe latency was seen after upgrade, and it was not possible to save business rule changes. This was traced to an issue with the decision rule being treated as a custom rule, and has been resolved by inserting a check. In addition, optimization has been added for queries on the pr_sys_decchg table.
