![]() ![]() It is important to realize that all other. The steps below outline how to configure the ASP.NET worker process to run with the identity of the ArcGIS Web services user and how to disable per request impersonation for the ArcGIS Server services and REST Web services. The burden on the lsass.exe process can be alleviated by altering the configuration of the aspnet worker process and the Web services or applications that are under heavy load. ![]() When a Web service or application that is impersonating is under heavy load (more than 25 simultaneous connections per second) for extended periods of time, the per request authentication operations begin to severely affect the memory and processing footprint of the lsass.exe process. Under normal load conditions, this authentication operation is insignificant. By default, these components impersonate the ArcGIS Web services account.Įvery time a Web service or application that uses impersonation handles a request, the underlying ASP.NET worker process must use the Local Security Authority Subsystem Service process (lsass.exe) to authenticate. The components of ArcGIS Server that handle Internet service requests, such as and are, themselves, Web services. By default, this is accomplished by configuring a Web service or application to impersonate with a specified identity, when handled by the aspnet worker process. NET must run as users in the AGSUSERS and/or AGSADMIN operating system group. Web applications and services that work with ArcGIS Server. This can cause system performance degradation and, in extreme cases, such as a heavy load over periods of 12 hours or more, machine shutdown. NET Web applications and Internet services are under heavy load (more than 25 concurrent requests per second), the Local Security Authority Subsystem Service (lsass.exe) system process can become overtaxed. ![]() Problem: On Windows XP, the Local Security Authority Subsystem Service (lsass.exe) grows in CPU usage and memory utilization under heavy load Description ![]()
