Summary

User traces a data page loaded with a complex activity involving a lot of loops on a voluminous data structure. User traces Run on a data page which uses a Connector simulation to load itself. The user also traces a test activity that is created to invoke the same connector. The connector is in the simulation mode. No issues occur in both the cases. However, the below stack trace displays in the logs on tracing the data page:

The Tracer causes death freeze of the session. The browser must be closed to be able to start a session and the previous session must be closed using the Admin portal. The data pages are traced incorrectly on Pega 8.1.1. However, they are traced correctly on Pega 7.4. This affects the activities. The activities are traced correctly on Pega 7.4 and traced incorrectly on Pega 8.1.1.

Nothing is traced while tracing a data page. Sometimes the technical activities related to running the data page are traced in the Tracer. However, the activity that is invoked to load the data page is not traced. However, nothing displays in the logs.
