CPU maxed out?

[Chris230291]

Can anyone make any suggestions on this? 14% isn't anywhere near what it should be.

Try looking at your processes (and their priorities) in your jail.
Give us that output. Try raising the process priority of your server.
(I'm just thinking out loud)

I had this same problem also up until about a week ago. I couldnt figure out what was going on to make this happen but i did fix it. What I did was unmount my HD's and then remount then. Strange as this sounds, it seemed to work. It went from literally 99.7% down to 3%..........weird. Anyway, give that a try, maybe it will help you as well

BTW - I'm not sure if you had this also, but my memory was being almost maxed out as well. I have 16G of ram and it was using 13.9G then, now its running at 265.4M. Substantially better

Good Luck!

That sounds useful. How do I do that?

Cheers,

Hi. I just detached my drive, then auto imported it again but it doesn't seem to have made a difference. Thanks for the reply though.

I forgot to mention that I tried setting up FreeNAS in a VM today to see if it was a hardware problem somewhere.
I downloaded and set up the VM image available from the downloads section. I then created my Jail and installed everything necessary for ArmA and ran it to find the same issue occurring. This suggests to me it's an issue with FreeNAS somewhere as a pure Ubuntu system running in a VM with the same specs runs perfectly.

Thanks,
Chris.

See if you can install something like htop for freebsd in your jail. I dont have access to a freebsd system atm :/

Ok I have installed htop now. I am running it inside a Ubuntu Jail again because running it in a FreeBSD Jail seemed to run marginally worse if anything and seemed kind of clunky.

This is what I see

Chris

EDIT: This is how it looks in my Ubuntu VM with 2 cores which runs great.

Did you ever find a solution?

My e3-1230 v2 never seems to go over 20% cpu either. I'm trying to transcode within an ubuntu jail via HandBrakeCLI which hits 100% on every other machine I've ever used it on.

 

[Chris230291]

Sorry no I havent. Maybe this is something that will suddenly start working in a future release. It's definitely a FreeNAS issue/configuration problem as I don't have any trouble in Linux. It's not hardware either as a FreeNAS VM has the same issue

 

[deanhuff]

When I run a transcode via HandBrakeCLI I'm getting 8 processes running, but only one loads the CPU to 100%. The rest just kind of sit there. I suspect the jail is configured to use a cpuset that only has 1 processor in it in my case.

I've got 8 logical cores. 8/1 gives me about 12.5% max usage...add the overhead of FreeNAS and that could land me at about 20% total CPU utilization.

I don't know where the jail configuration files live on the file system. I'll look around and see if I can find them.

I found that my jail is using cpuset 2. I believe it was via the jail command with a property to query cpuset.id: http://www.freebsd.org/cgi/man.cgi?query=jail&sektion=8&apropos=0&manpath=FreeBSD 10.0-RELEASE

I haven't yet found a way to see how many cpus are in a cpuset. If I have some free time tonight I'll try to get it figured out. From there, I plan to try to find a way to modify the cpuset #2 to add all of the cores.
