Create a massive traffic to the BIG-IP to consume entire TMM memory. Then due to lack of memory, the result pointer becomes null.


TMM restart.


- Using simple configuration with PBA, generating test traffic using T-Rex traffic simulator with simple HTTP GET use case. - The virtual server used during the test is /Common/vs-tcp-mbb- - First test generating cca 39Gbps, 123kCPS, generated 123k concurrent connections successfully, cca generated in time 11:11 to 11:13. - Second test generating cca 39Gbps, 123kCPS, generated 2.8M concurrent connections, TMM restarted after memory full, cca generated in time 11:16 to 11:20.
