LTM Default HTTP Retry Value

So we figured out how to fix this, and it's actually a very simple fix. In the pool's settings, go to the advanced menu, and set the Reselect Tries value to something other than 0. This will reselect a pool member for the request on a passive failure (i.e. connection refused) and retry the request. Our testing show that this works perfectly for us and solves our issue.
