If there isn't an active probe then the ACE will not be able to make reliable LB decisions. Without a probe current connections would hang and some new connections would be attempted subject to the predictor algorithm.
The ACE would not realise the server had died . If a specific port is used then your probe needs to test for it. Just using PING tells you you have a basic IP stack but not that a service is running.

Use a probe and decide on the correct failaction for your service.
