IP tuple nexthop object can be freed while still referenced by another structure.
The BIG-IP system might crash. This is a very timing/memory-usage dependent issue that is rarely encountered.
This can happen if LSN is in use and the proxy connection takes some time to complete, creating a large enough time window where the nexthop object might be freed.
None.
Management of IP tuple nexthop object reference counting is more consistent.
