Opened: Aug 25, 2025

Severity: 3-Major

Symptoms

1. Instead of crashing, TMM logs repeated Oops messages (ike_ctx tag invalid, ike_ctx_addr near NULL, traffic_selector_cfg sp_out required). 2. Can cause core, under low memory conditions, when multiple TMM threads run out of memory 3. Tunnel connections fail with thousands of logs. 4. BIG-IP does not crash, but repeatedly skips processing tunnel connections.

Impact

Tunnel connections fail repeatedly and can cause core, under low memory conditions, when multiple TMM threads run out of memory.

Conditions

Occurs on systems with long uptimes and when IPsec is configured.
