Hi all,I was running the previous 8.5.2beta domino (needed for the Traveler, also in beta in Linux) and it was running fine. Now that 8.5.2 officially appeared (and Traveler for Linux as well) i’ve updated both products to ‘Final Release’. Now, just after the restart of domino, i see high cpu usage (even when nobody tries to sync from a pda/smartphone).
Tasks concerned : http and traveler : eating 100% of the CPU (ask you can see from top ):
I’ve read that there are known issues for the SMTP task (the reason why i haven’t updated our 8.5.1 mail server to 8.5.2) . Is there also a known issue for Traveler ?
I don’t think Step 2 is really doing anything for you if the settings don’t save. Step 1 does bring the total processor usage down to 50% or so when compared to changing nothing. I think I found one better, though. While you have the Domino server running, open another terminal window, use su to login as root, and then open the java control panel. Give it about 15 seconds and then take a look at your processor usage again. If it does what I’ve seen here, you should notice it also, so please let me know what happens on your side. This also works without making the changes in Step 1, but of course the processor is pegged until opening the java control panel.
I’ve just removed Traveler from that server to see if it was Traveler or http related. Even after having removed traveler (and obviously having restarted domino), i still see that 100% cpu usage, but just with http.Can other people confirm ? or probably i’ll install a fresh (non upgraded) 8.5.2 server and see if it can be reproduced
I have not noticed this at all. I did set up a new Linux Box using CentOS 5 and installed domino 8.5.2 and Traveler 8.5.2 fresh. I have noticed that the host memory usage is up in the 1GB range but no CPU spikes as of yet.
I’ve got domino 8.5.2 running on CentOS with traveler and the latest SMTP fix applied and although everything works great, the CPU usage of the HTTP and TRAVELER tasks is maxed out.
I even went through all of the Domino Configuration Tuner recommendations, thinking I might hit upon something in the process. Really cool tool, but as far as this problem, not really any change.
Subject: High CPU on traveler, http and runjava tasks
I’m running a test-installation on a multi-core 64-bits linux system, and are seeing the same, over 100% (100% is 100% on 1 cpu core) load on traveler, http and runjava
System:
Lotus Notes Traveler 8.5.2.1 Build 201012031608 running on Lotus Domino server Release 8.5.2FP1|November 29, 2010 on a UNIX platform
From “top”:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

You should open a PMR for a systemdump and logs to be analyzed. This isn’t normal, so we’ll need to start there to figure out what is going on in your setup.
