When an NF loses heartbeat and enters re-registration, existing NRF subscription states tied to the previous NF instance remain both remotely (NRF) and locally (subscription_data pool). In environments with repeated heartbeat loss or timing races (e.g., docker-compose deployments), this leads to continuous re-subscription loops and unbounded growth of subscription_data entries, eventually exhausting the pool and triggering assertion failures in ogs_sbi_subscription_data_add(). This patch introduces a pre-registration cleanup mechanism: - Send DELETE requests for all subscriptions associated with the NF instance before re-registration. - Perform asynchronous local cleanup in the unsubscribe response handler (avoiding use-after-free and double free). - Add duplicate DELETE guard using subscription flags. - Improve logging visibility for subscription cleanup flow. This ensures that stale NRF subscription states are removed and prevents subscription_data pool exhaustion during re-registration loops. Issues: #4207 |
