RPC Application Processing Times
The RPC Application Processing Time exceeds the critical value set in Expert Thresholds. The "Application Processing Time" measures the time spent waiting for the application or server, as opposed to network latency. Network Latency plus application processing time is referred to as Session Delay, which is tracked by a separate Expert Threshold.
Possible reasons for the event:
The slowdown is probably the result of a server or application configuration issue. Perhaps the server hardware is overloaded with disk I/0 requests, or some other system component (for example, the CPU or NIC) is too slow given the traffic it is expected to handle.
The client and server that use RPC to communicate might also be a problem, either in the way that they have been configured by the user, or in the underlying source code.
