FIX: Cannot set the value of the "In-process messages" setting to 0 by using the BizTalk Settings Dashboard in BizTalk Server 2010

Article ID: 2662418 - View products that this article applies to.

SYMPTOMS

Assume that you have Microsoft BizTalk Server 2010 installed on a computer. When you use the resource-based throttling settings in the BizTalk Settings Dashboard to set the value of the In-process messages setting to 0, the operation fails.

Notes

The BizTalk Settings Dashboard is available in the BizTalk Server Administration Console.
The value of the In-process messages setting specifies the maximum number of unprocessed messages that can be delivered to the End Point Manager (EPM) or to the XLANG engine. The In-process messages setting is turned off if the value set to 0.
This issue does not occur in earlier versions of BizTalk Server.
If host throttling occurs when the number of in-process messages exceeds the threshold, the following information is logged in the Application log. To avoid receiving these events, set the value of the In-process messages setting to 0.
Log Name: Application
Source: BizTalk Server
Date: <Date Time>

Log Name: Application
