Since I’ve installed my Domino server, the memory increases in Windows Task Manager for all domino’s process (nserver.exe, nrouter.exe,…)
My server is installed with Windows 2000 Service Pack 4, Lotus Domino server 6.5.1 and Scanmail for Lotus Notes SP1 + HotFix.
When I watch the Windows Task Manager, memory used by domino’s task (nserver.exe,…) increases and crash my server (because memory is not desallocated for this process)
I’ve ever seen the same problem in this forum, but no solution were found.
I have a second server with the same configuration and the problem is also the same.
I noticed that when I show the console and after I reduce it in the Windows Taskbar, memory decreases immediately to take memory utilization at the start of the Domino server. But domino’s process start again to take all memory.
This is a well-known “feature”. You should always shrink the server console (or better only view the console from a remote machine, and have the server start on boot-up so there is no console visible on the server itself). Once you do this, the automatic memory-cycling features of Domino (which run every x minutes) will purge the redundant memory blocks. If you are watching in Task Manager, you’ll see the memory allocations slowly increase, then drop back down again.
In the end, it’s a problem with Windows that doesn’t fully release memory, so you should be rebooting your server weekly, or go over to a better operating system.

Thanks Henry !
But the server console which is running on my server is always shrink, and Domino server is running as services. The memory decreases when I click on windows taskbar to show server console and I minimise it.
I don’t know how to hide the console on my server.
I’m not sure that all persons who use Domino 6.5.1 on Windows 2000 have the same problem.
One thing you may want to look into is a corrupt system database. I have had experiences before where a corrupt log.nsf or mail file has caused certain tasks to consume more and more memory until the server falls over.
I also find removing all tasks from the Notes.ini then manually loading them one by one from the console helps to trouble shoot problem tasks/databases. If after loading a particular task your memory usage shoots up, yo are onto a winner.
I have more or less the same problem and as far as I understand there is a bug in releasing memory in Consoleapplications on Windows. I have created a small software that every hour minimize and maximize all Domino Servers so that memory will be deallocated. you can download the software from me at www.extranet.mcdonalds.se/consolewindowmemrelease.zip. At least this solved my problems
