What patch is addressing this change? And can could please explain a
bit more about what is needed to address the key cache corruption problem?

Right now I am working on a "reactive behavior" which tries to detect
a cache corruption event and subsequently re-install all the keys one
by one to ensure they are back to a proper state.

What does this ALWAYS_PERFORM_KEY_SEARCH bit do? Is it set within the
initvalues?

Sorry for shooting all these questions at once, but I am really trying
to understand how to properly address this issue.


Cheers,
