Hello CentOS ! Iam trying to configure a Dual Core 1.6Ghz AMD E-350 machine to be able NIC (eth0) interrupts the most efficient way possible so that I can be able to handle the large number of random source packets per second. Currently running CentOS 6.4 2.6.32-358.6.2.el6.x86_64, i made some load testing with a random sourced syn flood to the NIC of this machine and found out according to

I have a pretty large setup on one of my customers. Digium TE420B (with echo cancelling module), 3 Xorcom Astribanks with 32 FXS each and 1 Xorcom Astribank with 16 FXO. These FXO ports are NOT used for fax/data transmission, as they are connected to cell phones. Not really related to the issue, but there are also 250 SIP phones. The problem is that fax and dial-up connections are really

Hi, Does anybody have an idea as to why dahdi_test results drop to unacceptable levels after doing a wanrouter stop/start using a Sangoma card? See below that it drops from 99.99% to 98.55%: [root at bin]# dahdi_test Opened pseudo dahdi interface, measuring accuracy... 99.999512% 99.992874% --- Results after 2 passes --- Best: 100.000 -- Worst: 99.993 -- Average: 99.996193, Difference:

Hello, The harddisk of my etch/bristuffed asterisk1.2 box finally died. I moved the cheap (1397:2bd0) HFC-S card to a squeeze host (i686) and built dahdi modules 2.3.0.1 using m-a. After zaptel->dahdi and asterisk 1.2->1.6 config adaptations, everything seems ok, except for the BRI side, unable to bring layers 1/2 up. Asterisk reports: chan_dahdi.c:12393 dahdi_pri_error: 1 Unable to

Hello I've got small PBX (30 simultaneous connections) based on asterisk (1.6.2.6), which uses Stargate 2N ISDN to GSM gate.

Hi, I'm having trouble with one machine that kernel panics with Asterisk 1.4. The motherboard is an Asus P5W Deluxe. I reported the kernel panic here: http://lists.digium.com/pipermail/asterisk-users/2009-November/241006.html I'm now trying to understand if the problem can be an IRQ issue or not. I disabled APIC in the BIOS because I thought that maybe it could be buggy (not sure

I am running irqbalance with default configuration on an Atom 330 machine. This CPU has 2 physical cores + 2 SMT (aka Hyperthreading) cores. As shown below the interrupt for the eth0 device is always on CPUs 0 and 1, with CPUs 2 and 3 left idle. But why? Maybe irqbalance prefers physical cores? My understanding, though, is that the even-numbered CPUs are the physical cores, with the

Hello, I wanted to relaunch my problem with a quite precise and small question. Could the command "lsusb" affect interrupts when executing it regularly (cron) and if the zaptel pci card is sharing an interrupt with a usb bus? I have a Digium PRI card and a few Xorcom USB Devices. The Digium card seems to share the IRQ with some USB bus. cat /proc/interrupts CPU0 CPU1

Hi xen-users, I install xen, on gentoo linux. Install was ok, but i have an issue that i can''t solve. When booting in xen-linux, whereis no eth0 interface.

Hello all- I have a Digium TE410P in an HP DL145 G2 dual processor server that generates well over 100,000 interrupts per second (sometimes I?ve counted 160,000+ per second) generally resulting in either the system becoming swamped and unusable or the kernel disabling the IRQ the TE410P is on resulting in the spans on that card being unusable. I have confirmed that the card is good by placing it

Hi fellow asterisk users, I am running Asterisk 1.4.29 with an Digium TE121 card (wcte12xp kernel module) an approx. 100 snom320. The whole installation is running without issues since 5 months. Without having changed anything on the asterisk server for at least 2 months, i noticed "clicking sounds" at external calls over the PRI. Asterisk constantly throws the following messages: ...
