Web Tier busy threads released on timeout
Resolved in Pega Version 8.6.1
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.

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.

Out of memory condition resolved for BIX extraction
Resolved in Pega Version 8.6.1
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 8.6.1
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 8.6.1
Severe latency was seen after update, 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.

Handling added for disabling weekends when no weekends are available
Resolved in Pega Version 8.5.5
A browser exception was generated while selecting the option “Disable weekends”. This was traced to a malformed array of weekends in a scenario where the Data-Admin-Calendar instance had all business days checked (i.e., no weekends). To resolve this, DatePickerAssembly and pzGenerateDatePicker have been updated to handle the case when there are no weekends available in the Data-Admin-Calendar instance.

Added handling for reloading portal while ChatBot is active
Resolved in Pega Version 8.5.5
An issue was seen with UI rendering when a customer tried to reload the portal where the chatbot is deployed. Investigation showed that this was caused by the screen going to pyCreate harness instead of ChatPerform harness due tot he unexpected refresh, and has been resolved by updating the handling for the Chat Work page and the business case so that pyWorkPage is always Work-Channel-Chat.

Handling added for missing div when opening work object
Resolved in Pega Version 8.6.1
In mobile offline app, opening a work object in a specific scenario for the second time resulted in an endless busy indicator. It was not possible to navigate away, and the app had to be closed and reopened to continue. Investigation showed that some app sections had an action that tried to load a harness section where one specific div was missing, and this has been resolved by updating reloadSectionOSCOHandler to handle the missing div in the failure callback. Additionally a console.error() will appear for the missing section.
