FTP Application Processing Times
The FTP 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.
There is a hardware or software problem at the application end. Perhaps the FTP 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 or server is misconfigured in some way.
