My grub2-btrfs & yum-plugin-snapper

CDU load problems with testing
...ould solve my problems with the virtual network interfaceses (I cannot connect between two domains) and memory usage (I sometime "miss" a few hundret megabytes). The update didn''t help on the networking issues, but it did on memory usage. However, I created a new problem: using htop, the cpu is used at 50% in both dom0 and domU (running only 2 doms at the moment). However the load is 0.00 in dom0 and 1.99 in domU. AND Both systems process lists how no cpu usage... I think this is only a display issue in htop, but I need to be sure. So how can I for sure detect, if something i...

cgroup for VM - does it work properly?
Hi I tried to restrict usage of some running VM by cpu.shares (i.e. set to 10 from original 1024) on loaded system and it seem doesn't work as I expected... all running processes has same CPU usage (by htop) :-/ Does anyone has same experience? Fedora 19, libvirt-1.0.5.9-1.fc19.x86_64 Thanks a lot Martin -- Martin Pavlásek <mpavlase@redhat.com> OpenStack QA Associate/Red Hat Czech/BRQ irc: mpavlase

Windows Guest on KVM running "single core" after windows update
...are is a supermicro motherboard with dual Intel E5-2640 CPUs for a total of 40 threads and 64GB The guest is allocated 2sockets, 5cores, 2 threads and 32GB of RAM. (I've also tried 1 socket, 20 cores, 1 thread and 1s10c2t -- no help) In an SSH session to the linux host (CentOS7 - up to date), htop shows 1 core pegged and abnormal distribution of load (like it used to) even with fun little tools in Windows like the PowerToy -> CPUStress64.exe (i.e. the head CPU will show 90-99% and next thread in HTOP will show like 10% which then trails off to like 5%) Even if I tell CPUStress64.exe to...

Why so many worker threads?
Hello! Can anyone explain why my Unicorn installation (for RoR site) have so many worker threads? * screenshot: http://i.stack.imgur.com/U9TFR.png * unicorn.rb: https://gist.github.com/907th/4995323 Thanks!

Multiple cores are used in simple for loop
...very different behavior on the three machines: for(i in 1:1e6) {n <- 100; M <- matrix(rnorm(n^2), n, n); M %*% M} On the Ubuntu and Arch machine one core is used, but on the Debian machine ALL cores are used with heavy "kernel time" vs. "normal time" (red vs. green in htop). It seems that the number of cores used on Debian is related to the size of the matrix. Reducing n from 100 to 4 causes four cores to work. A similar problem persists with the parallel package and mclapply(): library(parallel) out <- mclapply(1:1e6, function(i) { n <- 100; M <- matrix...

Finding i/o bottleneck
Hi list ! We have a very busy webserver hosted in a clustered environment where the document root and data is on a GFS2 partition off a fiber-attached disk array. Now on busy moments, I can see in htop, nmon that there is a fair percentage of cpu that is waiting for I/O. In nmon, I can spot that the most busy block device correspond to our gfs2 partition where many times, it shows that it's 100% busy and is read all along. Now, I want to know what files are being waited for. With lsof I c...

Icecast eating 100% CPU
Hello, I am using the most recent stable icecast (2.4.3) with the following config: https://gist.github.com/mspanc/5e560e8fbd07bf65bc30a288cb514c14 From time to time, CPU usage hits 100% and keeps on that level once it’s hit. According to htop, only 20-25% is a regular usage (green bar on htop), rest are kernel threads (red bar on htop).   Am I doing some relaying and fallbacks as you can see in the config. *-silence mounts are streams that just play silence and they are synced to the clock. Is there something that is prohibited by th...

asterisk optimalization
hi, i'm testing asterisk 1.4/1.2 in the following scenario centos5/cpu quad xeon E5335 2.0Ghz - test clients behind nat - 1500+ testing instances - reregister option from 1min to 1hour - qualify set to 5000 top shows over 100% cpu. cpu cores sometimes go to 95% with htop i see ~16threads but only one child have ~95% cpu (how i can get info about that thread? what he is doing?) what is major bottleneck? qualify imho not. i'm tried set qualify=no, does not help SIP REGISTER packets? this problem persist if no calls are active after restart cpu usage slowly inc...

host freeze when starting VM
...emory and no other process is able to do anything. I have 16GB of ram in total. 8GB are reserved for hugepages. So for the daily business on the host I have 8GB left. I don´t run many or extraordinary consuming software on the host - normally just a gnome session and the chromium browser. Right now htop tells me that 10.1 of 15.4 GB are occupied, so that should be about 2GB, because I suppose 8GB are just reserved for the hugepages. I don´t have any swap space. In my latest attempt I gave a newly created VM 64MB of ram and this also brought the system down to its knees. So I would like to underst...

SBC's and ssh's encryptions
...ontrolling the program as it claims to be able to drive a 4k display at 30 FPS. I have tried running X on the raspi, but it hasn't enough memory or iron to do it well. With only a gigabyte of ram and running from a u-sd card for a boot drive, there is a hint of OOM to its failures. Running htop on the odroid, its not x but sshd thats the bottleneck thats causing the odroid to render at 3 or 4 frames per second at whatever the default encryption was. Last night, I went around and converted all my /etc/ssh/ssh_config's to: cipher chacha20-poly1305 at openssh.com This got me up to...

It depends on what backend R is using for linear algebra. Some will split large matrix calculations over multiple threads. On Debian, you can set...

Asterisk eating CPU
I have asterisk running user a user/group asterisk/asterisk like so su - asterisk safe_asterisk and one the processes utilizes way more CPU than any other. According to htop, it used 7:59:XX of CPU time. Once I kill asterisk and restart, another process does the same thing while others are running smoothly. This doesn't look like standard behavior to me. Is this some sort of a master process?

FW: [asterisk-dev] Hardware and CentOS tweaks.
...sure Asterisk and the OS takes advantage of these hardwares to make sure Asterisk does not bring the load averages up, or lock up, etc. Currently, while testing we see that one single CPU Intel quad core dialer with 2GB Ram uses all 4 "CPUs" in unison. Application used to see this was htop. We also ran the same amount of channels on the other dialer, i.e 500, which was a Dual Pentium 4 Xeon 3.2Ghz, with 2GB Ram and noticed on htop that one CPU, the first one was being used close to 80% whereas the other 3 CPUs are being used in unison around 20-30%. What do we need to know to be...

bizzare performance problem
I had a rather strange problem last week with one of our 8 core servers. The users complained the performance was "slow" so I checked the basic things, processes on top, vmstat for memory and context switching, i/o stats for internal disk I/O, netstat for any network issues and other things like network through put by copying a large file (1gb file across the network). It turned out I

Borderlands
...ided for installing Borderlands. Installed Wine 1.1.42 I believe is the version. I'm running Ubuntu Lucid. I installed the d3dx9 the vmc2005 and 2008 threw winetricks. activated the game threw the website with the licenses and stuff. started the installer. Killed the vmc2008 redist package with htop. killed the dxsetup.exe in htop. borderlands started installing everything was good. At the end of the install I get a fatal error and it stops. I'm assuming the install is complete because i can open the launcher and select play borderlands from the menu. When I do that though it seems to try...

problems with bind update of 9.8.2.0.10
Everyone, I have two x86_64 servers with CentOS 6.3 that seem to have some difficulty with the last version of bind : 32:bind-9.8.2-0.10.rc1.el6_3.2.x86_64 When I run htop I am getting a CPU usage of 70 to 80% all of the time. I am not seeing problems identified in the log files on either machine. This may have been present before the update of 9.8.2.0, but I certainly did not notice it. Has anyone else had this problem. Any solutions?? Greg Ennis

Samba crash (while logging in as administrator?)
...9 from yesterday) crash while logging in as administrator. The login stalled, and on the samba4 AD DC, winbind stopped responding -- "getent passwd" stopped showing the domain entries, and commands that showed some samba users (e.g. "ls" in a directory with domain owners, "htop", etc.) would hang. dmesg shows: traps: samba[3728] trap invalid opcode ip:7fbaaff2e780 sp:7fff6859f158 error:0 in libservice.so[7fbaaff29000+7000] I'll follow up if I can reproduce this, just wanted to start a thread in case anyone else sees this. - Nick
