With 'pva-acceleration' set to 'guaranteed', the BIG-IP system can take up to five seconds to detect that one of either the client-side or server-side connections has not been offloaded to the ePVA hardware.
This results in the connection that has not been offloaded being reset five seconds after being established.
This occurs with 'pva-acceleration' set to 'guaranteed' and only one of client or server connections is offloaded to hardware.
None.
FastL4 connections are now handles correctly with pva-acceleration set to guaranteed, and are no longer reset.
