Check for circular references added to SearchInventoryImpl to prevent recursive call
Resolved in Pega Version 8.4.2
An out of memory error was traced to SearchInventoryImpl infinitely recursing over a clipboard property, where the child property referenced a parent property and resulted in an endless loop. This has been resolved with the addition of a depth check to ensure that the search does not recurse infinitely.

Handling added for hotfix Rule-Application instances
Resolved in Pega Version 8.4.2
A null pointer error during DL file expansion performed as part of the second phase of a hotfix installation caused the hotfix install to fail. The null-pointer exception was thrown because the code, primarily used for export, performed a database lookup of a Rule-Application and assumed the response would be non-null without checking the result. During export the Rule-Application would normally exist because the system would have interacted with it already during the export by identifying it and writing it to the archive. During phased hotfix installation, rules are staged to the database in a different table during the first phase and reconstituted during the second phase. The scenario for this error was a missed corner case specific to the unusual combination of including Rule-Application instances in a platform hotfix. To resolve this and prevent further issues, handling has been added for this use case.

Hazelcast upgraded to resolve node startup issue
Resolved in Pega Version 8.1.8
Post data upgrade, the ADM tier failed to start and the error "java.lang.IllegalStateException: Node failed to start!" appeared. This was traced to a dormant bug in Hazelcast 3.11 that caused starting nodes to fail when the Hazelcast master node was shutting down, which was exposed by recent Pega changes made to enable parallel restarts of nodes in Cloud environments. Hazelcast delivered a fix for the parallel restart problem and the hotfixed jar has been merged into the platform.

Resolved Oracle thread deadlock for Merge SQL
Resolved in Pega Version 8.1.8
After starting a large cluster and running it for a couple of days, Oracle Deadlocks started to appear due to resource contention during MERGE SQL execution on the PR_INDEX_REFERENCE database table. The "ORA-00060: deadlock detected while waiting for resource" ERROR occur continuously every 10 minutes during the "MasterForNewAgents" Daemon run. All JVMs are impacted by the ERROR/Deadlock. Investigation showed that even though the identified / problematic Data-Agent_queue instances were disabled for PegaAESRemote, the MERGE SQLs continued to fire. To resolve this, an update has been made so the system will skip the copy of rule reference property from RAQ, while creating DAQ.

JobScheduler DST handling updated
Resolved in Pega Version 8.1.8
When the locale being used changed out of Daylight Savings Time, scheduled jobs did run at the same local time as before but instead ran an hour earlier than expected. Investigation showed that jobscheduler calculated the next runtime based on the time difference from the cluster reference time and current time in milliseconds, and this offset in milliseconds was added to next run time. Since the cluster was started in DST, the job was running on same time due to the time difference. To resolve this, the system will use a calculation offset and set hours/minutes to nextRunTime object so that calendar lib handles daylight savings.

Added expiration for orphaned tracers
Resolved in Pega Version 8.1.8
After tracing a REST service, the tracer was persisting but not showing in the requestor list from Admin studio. The operator shown in the error did not have access to the system anymore, and other users were not able to trace the service rule. Trying to clear the requestors in all the nodes using API POST /nodes/{nodeID}/pools/requestor/clear also did not resolve the issue. To address this, a distributed rule watch expiration has been added.
