Windows task manager will show a separate task for most Domino tasks. On our server, these Domino tasks can be seen in Task Manager:
– namgr.exe (3 of these, two for our two threads, one for an Agent Manager Executive task that controls the other two).
You should be able to look up information about these tasks. The Domino Administrator client shows corresponding tasks for most of these in the Server > Status > Server Tasks view. When the CPU overload occurs, review both the Task Manager and the Server Tasks view to determine what task is causing the problem. Also, ensure you are using the latest version of the server software. The condition you are experiencing may already be fixed in a later version.
