Correct service instance name passed for data flow in DSMStatus
Resolved in Pega Version 8.1.8
When using the Connect-HTTP service "DSMStatus" to provide the node and status information as seen on the various tabs of the Designer Studio > Decisioning > Infrastructure > Services landing page, using DataFlow as the service parameter for the HTTP service method resulted in an empty response when the expectation was to get the information regarding the cluster details of Dataflow node type. This was traced to the service instance name not being parsed correctly when used for Data Flow services, and has been resolved by ensuring the correct service instance name is passed for this use.

Statistic rounding error in ADMSnapshot Agent with Oracle corrected
Resolved in Pega Version 8.1.8
While running the ADMSnapshot Agent, the exception "internal.mgmt.Executable) ERROR com.pega.decision.adm.client.ADMException: Failed to complete ADM Data Mart snapshot" was seen. This was traced to an issue with the rounding of performance statistics when using Oracle, and has been resolved.

Deadlock in static Initialization of IntList resolved
Resolved in Pega Version 8.1.8
JVM Deadlock was seen related to the static Initialization of a subclass field in class com.pega.decision.strategy.ssa.runtime.collections.api.IntList . Thread dumps showed threads in RUNNABLE State that were parked to wait for class initialization, and this was traced to a missed sonar alert which failed in multi-threading. To resolve this, the system handling has been updated to prevent potential deadlock.

Performance and thread-handling improvements for SSA
Resolved in Pega Version 8.1.8
The SecureRandom class was used internally by SSAExecutionContext indirectly via UUID generation. Because this exhibited performance issues on some Linux environments, UUID has been replaced with static AtomicLong. In addition, a memory leak was observed when the strategy (SSA) execution resulted in an exception, and the strategy template has been modified to gracefully shutdown the VM under all circumstances. Thread-safety measures have also been tuned to be more fine-grained to reduce the potential thread contention that was seen while borrowing the SSAInterpreter object from SSAInterpreterPool.

Timing updated for Cassandra session change thread lock
Resolved in Pega Version 8.1.8
An issue with unresponsive nodes was traced to the method used for notifications about Cassandra session changes. A thread trying to obtain a Cassandra session acquired a read lock, then if it then determined that a new session had to be created it would also acquire a write lock, preventing other nodes from trying to acquire the session. After creating a session, the thread notified all session change listeners while holding the write lock, causing deadlock with dependent services. To resolve this, the timing has been updated by moving the session change notification to the listeners outside of the section guarded by the lock.

Updated COUNT logic for strategies with ssavm set to true
Resolved in Pega Version 8.1.8
An error was seen when attempting to save a strategy after setting ssavm to true, indicating an issue in the “COUNT” method in Group By shape. Since the source field is not used and does not need to be evaluated here, the system has been updated to ignore the source field if the operation is COUNT.

Breadcrumb functionality disabled for Process Modeler pending further development
Resolved in Pega Version 7.1.8
Some complex installations experienced OOM events and crashes when opening flows in Process Modeler that contained nested levels of nested sub flows. The root cause of this problem was code that allowed excess data to be opened into the clipboard for every sub flow that could potentially be run as a result of running the top level flow. To prevent this problem, breadcrumbs functionality has been disabled at this time. The canvas viewer is being rewritten for ML9 together with a new implementation of multi-level process navigation in order to resolve this issue.

Appearance order retained for multiple swimlanes
Resolved in Pega Version 7.1.8
After putting multiple swimlanes in a flow, the order of their appearance was returning to the original state after saving it. This was caused by the rendering being performed in the order the server store/sent the swimlane data. To ensure proper behavior, the swimlanes are now reordered based on the swimlane layout (horizontal, vertical) and their coordinates before being rendered.
