Dear List Users Greetings, i have come across the problem where CentOS 6.3 x64 has more than 700 processes running. i am not sure where to start, what in normal or abnormal.

Asterisk users, I posted the following email to the Fedora users list <https://www.redhat.com/archives/fedora-list/2006-March/msg04154.html> and it got no responses, so now I'm calling on your expertise. Please take a look at it and share your knowledge on the subject with me. Additionally, let me know if you believe what I am trying to do is critically flawed. It's possible

Hi Team Can someone advice me on how i can lower the load average on my asterisk server? dahdi-linux-2.1.0.4 dahdi-tools-2.1.0.2 libpri-1.4.10.1 asterisk-1.4.25.1 2 X TE412P Digium cards on ISDN PRI Im using the system as an IVR without any transcoding or bridging ************************************** top - 10:27:57 up 199 days, 5:18, 2 users, load average: 67.75, 62.55, 55.75 Tasks: 149

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":

Hello, I was wondering if anyone could tell me why so many processes are started on my system? Here is a list of them. I am trying to figure out why they are running and if I can stop them. Thnx.

I am hoping that someone has had better luck with this than I have. I would like to connect Cisco 7940s and 7960s to the Netgear FS116P, and take advantage of its POE. I know that the Cisco phones use Cisco's "pre-standard" POE implementation, but as I understand it the difference is really only two pins. I bought a bunch of PowerDsine inline power adapters which supposedly change

So, I have a server at home that has four VMs running inside it. All are managed via puppet. The physical host runs puppetmasterd. I don''t recall noticing this before, but puppetmasterd has decided to be kind of crazy.

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

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

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

Could anyone either recommend a website or howto on optimizing Linux to run asterisk. Such examples of what I mean are.. Renice of asterisk pid's Forcing irq smp_affinity (For interupt hogging T1 cards) .. That kind of stuff, I looked on the wiki and nothing directly mentions server optimization. Or, is this something that *should* be totally irrelevent when dealing with Asterisk. P.S. I

Hi, Just trying to figure out / solve some echo issues with one of our systems. The server is a Dell R710 running Asterisk 1.6.x and Dahdi 2.2.x The card in the server is a TE121P (with VPMADT032 echo canceller) We are experiencing some weird echo issues with our Cisco 79xx phones, only when we are dialing out via the PRI. The echo is like a side tone, where we can hear ourselves speaking. The

I am trying to get to the bottom of audio clicks, pops, dropouts with my Asterisk server. These occur even when the system is under minimal load (e.g. 1 Zap device in a queue being played music on hold) and occurs with both Zap and Sip devices so isn't network related. The audio problems occur at the same time on all channels and seems to be when Asterisk "gets busy" and uses
