In long-running deployments, a mismatch can occur between SMF’s stored Gx/Gy/S6b Session-Id and the freeDiameter session table, typically after peer reconnection, watchdog timeout, or internal cleanup. In such cases `fd_sess_fromsid_msg()` may return `new != 0`, indicating that the Diameter stack created a new session instance instead of retrieving the existing one. Previously, this condition triggered `ogs_assert(new == 0)` which caused a fatal crash of the SMF (and potentially SGWC), interrupting normal operation. This patch replaces the assertion with a graceful recovery path: - Log an error indicating that the Diameter session has been lost - Free the pending request message and stored Session-Id - Return early to trigger PDU session release handling by the upper layer - Avoid process termination and maintain service continuity This significantly improves robustness in long-running and fault-tolerant deployments with commercial-grade operational requirements.
