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