Subject: Nserver.exe drains CPU

Feedback Type: Problem

Technical Area: Administration

Platform: Windows 2003 server

Release: 8.0.1

Reproducible: Always

Hi,

I have a problem with one of the servers within our infrastructure.

We have had Domino 8.0.1 running on the Windows 2003 server and there have been no problems until recently. We now find that one of the users running Notes client 7.0.3 shows has having mutliple connections to their mail file under the Server->Status->Notes Users view.

Looking at the server, CPU usage is at 100% and the process eating this up is nserver.exe. This dramatically affects the performance of the server and for all users connecting to this Domino server as you would expect. The only fix we know of to clear this problem is to restart the Domino server. After a restart, CPU usage goes back to the expected/normal rate (doesn't usually go over around 40%).

After an hour or so, reports of the Domino server being slow filter through again and sure enough, CPU usage is back up to 100% again, and once again the same user shows has having multiple connections to their mail file again.

Any advice or pointers as to why nserver.exe is eating up the CPU would be greatly appreciated.

Thanks,
Chris
