Symptoms

If one of the default adapt profiles, requestadapt or responseadapt, is applied to the virtual server but an internal virtual server is not selected, then over time memory usage may increase and connections may be killed to reclaim memory.

Impact

Over time memory usage may increase and connections may be killed to reclaim memory.

Conditions

A virtual server has requestadapt or responseadapt default profiles but does not select an internal virtual server.

Workaround

Do not apply the requestadapt or responseadapt profile directly to a virtual server unless you plan to associate an internal virtual server via an iRule. If adaptation is desired, either make a new adapt profile inheriting from one of these defaults and select the name of an internal virtual server that exists, and/or use the ADAPT::select iRule to select an internal virtual server. If adaptation is not desired, remove or do not add an adapt profile.

Fix Information

An adapt profile without an internal virtual selected will be treated as if it is disabled. This is correct behavior.
