How to detect when a generated stream was overwritten but never sent (PEGA0031 alert) How to detect when a generated stream was overwritten but never sent (PEGA0031 alert)A PEGA0031 alert is generated when a starting activity or stream has generated multiple response streams during a single interaction. If multiple streams are generated, then only the last one is sent to the workstation browser (client).
System resources were used to generate the previous screens with no benefit to the interaction. Here is an example of the message:
Overwritten HTML stream
This alert has no configurable settings.
Analyze the activity that the triggered the alert. Examine the last step, initial activity, and the trace list in the alert to determine what streams are being generated during the interaction. Remove any unnecessary generations.
