Description (partial)

1. Packet tracer fails with message: "ERROR: TRACER: NP failed tracing packet"
2. Capture with trace fails to show any trace information for captured packets and displays the below message :
"WARNING: The tracer pool is exhausted. Capture with trace option will not be able to display the trace. Capture with type asp-drop will not be able to include all drop reasons. To recycle tracers back to the pool, please clear or unconfigure the above types of captures."

1. asp drop or interface captures applied with trace keyword.
2. the captures could have been applied in the past and the tracer pool will be exhausted over a period of time.

They need not be configured while the issue is happening.
