SYMPTOMS
The Microsoft BizTalk Server 2004 File Adapter may cause a NonPagedPool memory leak by issuing too many input/output request packets (IRPs). The possibility of the memory leak increases with the number of receive locations that use the File Adapter.
To verify that your BizTalk Server-based server is experiencing a NonPagedPool
memory leak, use Performance Monitor to monitor the following
counters:
- Object: Memory
Counter: Pool Nonpaged Bytes - Object:
Process
Instance: BTSNTSvc
Counter: Pool Nonpaged Bytes
In some extreme cases, when all available system NonPagedPool
memory is used up, you may receive an error message that is similar to the following in the System log on your BizTalk Server-based server:
Event ID: 2019
Source: Srv
Description: The server was unable to allocate from the system nonpaged pool because the pool was empty.
If you receive this error message, your BizTalk Server-based server may stop responding (hang).
Additionally, your BizTalk Server-based server may restart if the
Automatically restart option is enabled on the
Startup and Recovery dialog box that you can open from the
Advanced tab of the
System
Properties dialog box. To access the
System
Properties dialog box, right-click
My Computer, and then click
Properties.
