Symptoms
The Zero Window timeout property of the TCP profile cannot be modified on an internal virtual IP, like the one used by APM hosted content.
Impact
If a large file is hosted on APM client, there is a chance that the TCP window will fill up on a slow connection, and after 20 seconds of zero window, the connection will be reset.
Conditions
Any internal VIP.
Fix Information
The TCP configuration for HTTP forwarding internal virtual server can now be modified using these TCP profiles: 1. apm-forwarding-client-tcp for client-side connections and 2. apm-forwarding-server-tcp for server-side connections.
