Bug #: 50001802 (SQL Hotfix)
Microsoft distributes Microsoft SQL Server 2005 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2005 fix release.

SYMPTOMS

Consider the following scenario:
  • In Microsoft SQL Server 2005, you create a Service Broker application.
  • The Service Broker application has message forwarding enabled.
  • You try to send a message to the target service of the Service Broker application.
In this scenario, the message is not sent to the target service. Additionally, you may receive one of the following time-out error messages:
Error message 1
This message was dropped because it could not be dispatched on time.
Error message 2
This forwarded message was dropped because the message could not be delivered within the message time to live.

CAUSE

This issue occurs because SQL Server has timed out. In the forwarding instance, there is a limit on the time that can elapse between when a message is sent and when the message is received. If the forwarding instance does not receive the message within the time limit, the message is dropped.

The time counter should start when the last byte of a new message is received. However, the time counter starts when the first byte of a new message is received. Therefore, you always receive a time-out error message if SQL Server takes a long time to receive a message.

RESOLUTION

The fix for this issue was first released in Cumulative Update 4. For more information about how to obtain this cumulative update package for SQL Server 2005 Service Pack 2, click the following article number to view the article in the Microsoft Knowledge Base:

Note Because the builds are cumulative, each new fix release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2005 fix release.
