MOM Rule Name

Client: Averaged client RPC latency is greater than the specified threshold.

Explanation

This Warning event indicates that a Microsoft Outlook client computer is reporting long latency remote procedure calls (RPCs) to this Microsoft Exchange server. Potential causes include:

  • Server resource bottleneck (for example, disk or CPU)

  • Network problem

  • Problems on the client computer

User Action

To resolve this warning, determine if the long latency is on the Exchange server or is external to the Exchange server. Do one or more of the following:

  • Look at the average RPC Latency view to determine how long the server is taking to process RPC requests.

  • Look at the Number of Slow RPC Packets view to see how many RPCs took longer than two seconds to process on the server.

If the average RPC latency is short and there are few long RPCs, this is an indication that the problem is external to the Exchange server, such as a network bottleneck.

If the average RPC latency is long or there are many long RPCs, this is an indication of a resource bottleneck on the server. Investigate the typical sources such as disk latencies, queues, or CPU utilization.
