Hi Ron, I had the same issue , mine was because the server was under power , Traveler is a memory hog and I would suggest to use 16GB for 1000 users. When I have 8GB , often CPU climbs up to 100% and start having performance issue.

Thank you for the information Riko. I will review, make some changes and see what happens.

I currently have some 100 Traveler devices and running Domino on Windows 2008 R2 Enterprise Virtual server (VMware 4.1).

Thanks again

This is not working for me....

I am reviewing the number of HTTP threads and will increase there to 400. The server is running both Traveler and also webmail.

Anyone else out there have a view on what else may need to be done?

Thanks

Thank you for this additional information. I am currently in contact with IBM Support and will monitor my system.

General tip for troubleshooting high CPU issues...

(1) Enable standard debug:

DEBUG_SHOW_TIMEOUT=1
DEBUG_CAPTURE_TIMEOUT=1
Debug_ThreadID=1
CONSOLE_LOG_ENABLED=1

(2) generate a manual NSD during the problem.

(3) To accompany the NSD, collect screenshots capturing the thread that is consuming the high CPU.

Windows:

Download and install "Process Explorer" from Microsoft (http://technet.microsoft.com/en-gb/sysinternals/bb896653.aspx)
Launch Process Explorer and do the following:
 (1)  doubleclick on the task(s) that is consuming the high CPU resources to display the task's details window in the bottom pane
 (2)  whilst still highlighting the task in the top pane, right click and open its properties and select the Thread's tab
 (3)  please take a screenshot of everything in the bottom and top window panes of the Process Explorer and another screenshot highlighting the task's Thread properties.

UNIX:(this example of for Linux)

Launch the following command

a. detect the process & pid by issuing the following Linux commands:
ps auxw | sort -r +2 | head -10

Run "top", then press K
You'll have the %CPU column organised. Obtain the PID that is consuming the most CPU.
Then run the following to get the Thread ID TID info for the process:
ps -p <pid> -L -o pid,tid,psr,pcpu

Send the data to IBM Support.

With this data at hand, IBM Support will be quickly able to isolate the specific thread that is causing the CPU spike and using the NSD, they can review the offending thread's call stack which can speed up time to resolution for your problem.
