Also die Auslastung der CPU liegt im normalfall auch nur bei ca. 10%. Nur in diesem Fehlerfall liegt sie bei 50-60%

OS ist Win2003 Server

Abstract
Domino 6.x running on Windows 2003 takes hours to shut down and experiences periodic slowdowns.



Content
This issue was reported to Quality Engineering and has been addressed in Domino 6.5.2 Fix Pack 1 and Domino 6.5.3 Fix Pack 1.

Excerpt from the Lotus Domino Release 6.5.2 FP1 and 6.5.3 FP1 fix lists (available at http://www.ibm.com/developerworks/lotus):

Server
SPR# RCE5X7QY5 - Windows 2003 performance: Implemented a code workaround to a Microsoft issue under Windows 2003. This issue would cause the server to take a long time to shutdown. The server would also experience slowdowns while the Domino server is running as tasks shutdown i.e. Compact. In order to realize this fix, you must implement the Notes.ini parameter Debug_Skip_UnmapViewOfFile=1 on the Domino Server. This parameter should only be implemented on Windows 2003 servers. We also recommend migrating to Windows 2003 SP1 when that is released. This problem has been fixed in 6.0.5, 6.5.4, 6.5.3 FP1 and 6.5.2 FP1.

Microsoft Support has verified this is a Windows 2003 performance issue related to the function call UnMapViewOfFile. This same issue impacted Windows XP SP1 and is described under Microsoft Article #815227. Microsoft has indicated that the issue is addressed in Windows 2003 SP1, which has now shipped:

http://support.microsoft.com/default.aspx?scid=kb;en-us;889100

As a workaround, some customers have had success using the following Notes.ini parameter on the server, to limit memory usage:

ConstrainedSHMSizeMB=<x>

where x=the number of megabytes of shared memory to which Domino is constrained.   ConstrainedSHMSizeMB=700 worked for one customer on a machine with 4GB of RAM.

Supporting Information:
Why is Domino and only a few other software products affected by this? Domino is using an API call that tells the Server OS to begin de-allocating memory for a task at the point it no long needs the memory. This is done to speed up the release of the memory and is considered good software coding. Eventually the OS would de-allocate this memory when it does its normal housekeeping. Unfortunately in this case, this exposes the issue in the Microsoft server OS.
