If you had a second monitor watching tcp/808, then the loss of that port would also take the pool member down.
If there are no pool members available, then the virtual server will go down. However, if there's an irule attached to that server, which references another pool, the virtual server will remain up, even with no pool members. The thinking here is that the irule might send the traffic to another pool member that is still up, so we need to keep the virtual up, so that the irule gets a chance to run.
So with that in mind, you could create an irule that looks at the number of members active, and redirects to another page or pool member if that is case. Probably something similar to this
Of course this all depends on whether your application is smart enough to handle such a response in an intelligent way when you send it unexpected data.
