Symptoms: A router crashes when an RTR probe is configured.
Conditions: This symptom is observed when the RTR and the fallback system process are not
synchronized. For each RTR probe, the fallback system creates a cache entry and keeps it for cache
timeout. During the cache timeout, the fallback system process sends an event to RTR and frees the
entry, but RTR sends an event after the cache entry is deleted.
