In certain circumstances, CMP demoted Fast L4 virtual servers may intermittently and incorrectly use the tcp handshake timeout instead of the configured idle timeout.
Connections may be reset earlier or closed at an unexpected time.
- CMP demoted Fast L4 virtual servers.
Ensure that the virtual server is not CMP demoted. To do so, do one of the following: -- CMP-enable the virtual server. -- Ensure that any iRules that CMP-demotes the virtual server are corrected. See SOL13033: Constructing CMP-compatible iRules at https://support.f5.com/kb/en-us/solutions/public/13000/000/sol13033.html
CMP demoted fastL4 VIPs now correctly use the idle timeout.
