  2. The Oldest Message Queued performance counter in Exchange 2000 Server displays a very large value when the queue is empty

The Oldest Message Queued performance counter in Exchange 2000 Server displays a very large value when the queue is empty

View products that this article applies to.

Symptoms

When you log instances from the Oldest Message Queued performance counter for the MSExchangeMTA Connections performance object on your Microsoft Exchange 2000 Server computer, you may experience one or both of the following symptoms:
  • If you use the Windows Performance tool in Microsoft Windows 2000 Server to log these instances, the Windows Performance tool reports very high values. Sometimes, these values may indicate that the oldest messages have been queued for as long as several years.
  • If you create a program to access the Performance Data Helper API of the Pdh.dll version 5.x redistributable DLL to log these instances, a 0x800007d6 error code is returned.

Cause

This problem occurs if the message transfer agent (MTA) queue does not contain any messages.

When an MTA queue contains a message, the MTA updates a counter with the current date and time stamp. When you add the Oldest Message Queued counter to the Windows Performance tool, the message in the queue continues to age as it sits in the queue. The Oldest Message Queued counter helps you determine how many seconds the message has been in the queue.

If the queue is empty, the performance counter still exists, but the MTA sets its value to zero.

The Microsoft Windows NT Server 4.0 Performance Monitor tool correctly displays this value as zero. However, the Windows Performance tool and Pdh.dll incorrectly display this value as the decimal value of the current sampling time stamp.
