Missed RPC deadlines

As a server becomes overloaded, its responses to RPCs from its clients arrive later, which may exceed any deadlines those clients set. The work the server did to respond is then wasted, and clients may retry the RPCs, leading to even more overload.

Reduced CPU caching benefits

As more CPU is used, the chance of spilling on to more cores increases, resulting in decreased usage of local caches and decreased CPU efficiency.

Memory

If nothing else, more in-flight requests consume more RAM from allocating the request, response, and RPC objects. Memory exhaustion can cause the following effects:

Dying tasks

For example, a task might be evicted by the container manager (VM or otherwise) for exceeding available resource limits, or application-specific crashes may cause tasks to die.
