The recommendation is not to exceed 1000 Agents per SS. I generally use a MAXIMUM top load of 1500 Agents per SS. At 2400+ you are VERY likely to see problems related to CAM queues, which may very well be the cause of your SDSERVER crashes.
Unfortunately adding more or faster CPUs or more RAM does not affect this number. The maximum load for an SS has more to do with the number of queues CAM can effectively handle and this number does not increase with more RAM or faster CPU, it is a limit based on CAM technology.
FYI – these numbers may actually need to be LOWER based on other requirements such as service level agreements for package delivery.
