IIS Out-of-Process Applications Stop Responding (328693)
The information in this article applies to:
- Microsoft Internet Information Services 5.0
This article was previously published under Q328693 SYMPTOMS When an application is configured to run out-of-process
(that is, in medium or high isolation), the application may stop responding
(hang) or cause Web browser requests to time out. Refreshing the browser
appears to correct the problem, but the problem appears more frequently with a
heavier load on the server. CAUSE This occurs in the Dllhost.exe process that is hosting the
application because Asynchronous Procedure Calls (APCs) can inadvertently alert
a worker thread that is responsible for cleaning up Web Application Manager
(WAM) requests. When this occurs, the WAM_REQUEST and WAM_EXEC_INFO objects can be leaked. RESOLUTIONService Pack InformationTo resolve this problem, obtain the latest service pack for Microsoft Windows 2000.

Hotfix InformationTo resolve this problem, obtain Microsoft COM+ Rollup Hotfix
23. WORKAROUND To work around this problem, set the application protection
for the application to Low. When you do this, COM+ does not have to marshal
data between the Inetinfo.exe and Dllhost.exe processes. STATUSMicrosoft has
confirmed that this is a problem in Microsoft Internet Information Services
5.0.
This problem was first corrected in Microsoft Windows 2000 Service Pack 4.
