      Are you using Performance L4 VS? If yes, remove HTTP Profile. 

      If not, the message may indicate that the response received from the back-end server is not RFC compliant. You should first and foremost modify and correct the back-end server behavior. There is a workaround to change this while you wait for your backend to comply to the RFC.

      Impact of workaround: The impact of the suggested workaround depends on the specific environment. F5 recommends testing any such changes during a maintenance window with consideration to the possible impact on your specific environment. A testing environment would be ideal.

      1. Log in to the TMOS Shell (tmsh) by entering the following command: tmsh
      2. To enable the tmm.http.passthru.invalid_content_length database key, enter the following command: modify /sys db tmm.http.passthru.invalid_content_length value enable
