Title: 2.4 CPU usage unusually high Post by: wjstone on Sunday 30 May 2010, 07:17:56 am Just installed 2.4 on a brand new Foxconn Atom board with 1 gig of RAM. With no services turned on except for DHCP the CPU usage on both processors is sitting at 97%, RAM usage is 9%. Anyone else having this problem? Not sure why the CPU would be so high.

help me please along the way use console Edit the /usr/local/bin/rrdfix.sh script and remove the /var/ntop from the DIRS variable. run rrdfix.sh script thats it or did i miss something? thanks!

its a cf card 133 DMA speed. was not a problem with 2.3 But i am thinking to put a SSD in if this is the case. Its mostly the %wa state. Funny is as soon as i start copying from green to green wa% goes down. thanks!

EMI = endian management interface (webserver GUI) ?? collectd http://bugs.endian.com/view.php?id=2585 collectd is a lighweight, modular daemon that collects system performance data Dashboard? so better close the admin gui to safe resources ?!? :-S collectd is running most of time (schedule for perfomance checking?) together with monit Title: Re: 2.4 CPU usage unusually high Post by: arminf on Tuesday 01 June 2010, 05:09:52 am High Percentage in %id CPU State
Programs which make use of CPU Idle Time mean that they run at a low priority so as not to impact programs that run at normal priority. Many programs that use CPU idle time cause the CPU to always be 100% utilized, so that the time spent where the CPU would have been idle is instead spent performing useful computations. This generally causes the CPU to consume more power as most modern CPUs can enter power-save modes when they are idle. Not good for an ATOM CPU....

Title: Re: 2.4 CPU usage unusually high Post by: wjstone on Friday 04 June 2010, 06:11:43 am I think it could be the disk, or maybe ram. How much RAM do you have in that machine? I wonder if it's trying to write things to swap and that's causing the issue.
Title: Re: 2.4 CPU usage unusually high Post by: arminf on Friday 04 June 2010, 07:43:37 am Thanks WJStone
2 GB Ram and swap is always empty. Disk is a CF crad 133 UDMA Could also use Sata thought about buying a ssd. cheers Title: Re: 2.4 CPU usage unusually high Post by: wjstone on Saturday 05 June 2010, 12:31:46 am I dunno man that's pretty strange. I was hoping you were just writing to swap and that was doing it. Seems that isn't the issue. Have you tried installing the respin that came out a few days back?
Title: Re: 2.4 CPU usage unusually high Post by: arminf on Monday 07 June 2010, 03:23:06 am Hi wjstone
yes i use the respin version. must be snort leated as my network traffic slowed down, too. cheers Title: Re: 2.4 CPU usage unusually high Post by: icebrian on Tuesday 19 October 2010, 10:49:01 pm Hello everyone...
I am in need of urgent help... i've just upgraded from 2.2 to 2.4 and I am getting the high CPU usage bug from ksoftirqd. rrdfix.sh fix doesn't seem to solve problem. Swap is at 0 and firewall is so unresponsive that I can't get an ip via DHCP or access webinterface. How can I disable do the steps: 1- Disable Traffic monitoring (ugh!) 2- Configure Traffic Monitoring to only catch data of your local hosts. eg 192.168.0.0/16 Without accessing the webinterface? or any other ideas? Thanks, Title: Re: 2.4 CPU usage unusually high Post by: icebrian on Wednesday 20 October 2010, 03:20:57 am Ok well in an attempt to fix this issue I decided to do a clean install of v2.4. Aparently error is still there, I was therefore forced to go back to v2.2.
