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

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.

Resolution

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
