You can adjust the buffer size of the Tracer header to increase the limit for unprocessed events. By default, the system saves up to 50,000 items for unprocessed events during a Tracer operation. If the buffer exceeds this limit, Tracer processing ends.

• Tracer event queue overflows

  Each Tracer session uses a file buffer that holds up to 500 events not yet processed for display. Some complex tracing situations reach this limit and additional events are discarded.
