BIG-IP system software allows you to cache HTTP responses with WAM/AMM web applications. There is a special storage location for small-size objects. If a caching object is about to exceed a threshold limit, the BIG-IP system might change its caching storage to MetaStor. A fix for ID 792045 introduced an issue for instances in which it does not, which resulted in not serving a cached object.


The BIG-IP system resets a connection with an error, a cached object is not served, and the rendering of a client's webpage is not correct.
