An internal virtual server might behave in unexpected ways, such as abort a client connection before connecting to the server.
The internal virtual server might sometimes abort when attempting to make a connection to the server. This occurs after a successful load-balance pick indicated by the LB_SELECTED event, but before a TCP SYN packet is sent to the server. As a result the parent virtual performs the service-down-action configured in the request-adapt or response-adapt profile.
Virtual server with request-adapt or response-adapt profile and a vlan with 'cmp-hash' mode 'src-ip'. Internal virtual server without a VLAN or 'cmp-hash' setting.
If possible, do not use the cmp-hash mode 'src-ip'.
An internal virtual server is not affected by any 'cmp-hash' mode setting in the parent virtual server.
