similar to: 25% cpu usage during idle

I'm seeing some strange results from top on CentOS 4.0. When it first starts, it reports low CPU usage. The next refresh (and subsequent) refreshes, it shows high CPU usage. In both cases, there is nothing shown in the process list that is using much CPU. What is causing this? Here is some truncated output from a single run of "top -b -n 2":

Over the past few months, I have seen many postings here about runaway smbd processes with Samba versions 3.0.20 and above. Personally, it never happened to me until today. Also, I have stuck with Samba 3.0.13 on most of my machines because of THIS reported issue and a couple of other issues that I have experienced. However, I have a machine running RIGHT NOW where smbd has gone out of

List, The past few days the asterisk service on my server has crashed several times. I have had it running for months and have made no changes to it. When it crashes, I am unable to make calls or gain access to the CLI. The service has been stopped. If I try to start it again (service asterisk start), it will start and run for a few seconds then crash again. After a reboot, it will run

Hello List! I got a small (50mbits or so) application layer ddos attack against a few name servers (thousands of IPs sending lots of bogus A record requests - weird) - one of the name servers was behind a shorewall firewall. That firewall was running a 2.6.18-194.11.1.el5 kernel and shorewall-4.4.11.1-1. I noticed that the shorewall host had ksoftirqd using 100% of the CPU during the

I hope this in the right list, but I was wondering if someone could help me with a VM I have that has lately started having problems. It had been running for years without problems. It's possible an update is causing this, but I can't say. The VM is running CentOS 5.8 and after a time, the machine begins to slow down. Things like pings or running commands lag. If I reboot the VM, it runs

Hi, I recently updated from puppet 3.1.1 to 3.2.1 and noticed quite a bit of increased load on the puppetmaster machine. I''m using the Apache/passenger/rack way of puppetmastering. Main symptom is: higher load on puppetmaster machine (8 cores): - 3.1.1: around 4 - 3.2.1: around 9-10 Any idea why there''s more load on the machine with 3.2.1? -- You received this

Hi, I am running Fedora 7 VM. On an earlier configuration with zaptel and Asterisk 1.4.21 , meetme worked alright. I upgraded to Dahdi and Asterisk 1.4.26, and the result is choppy sound via Meeme, while a simple Musiconhold works OK with descent audio quality. So I am sure its a Dahdi_dummy problem. Running dahdi_test gave me very poor results. Opened pseudo dahdi interface, measuring
