You can adjust the buffer size of the Tracer header to increase the limit for unprocessed events and prevent Tracer processing from ending.
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.
<env name="tracer/queue/type" value="file" />
<env name="tracer/queue/file/limit" value="
<env name=" tracer/queue/header/limit" value="nnnnn" /
where nnnnnis a nonnegative integer.
Note: As an alternative to updating the prconfig.xml file, you can use Dynamic System Settings to configure your application.
