Re: [asterisk-users] 2 PRI Card - Interrupt Problem
Yep, that's a known problem with older CentOS version. I have some 6.4 customer machines, which I cannot update easily, so I wrote a little patch for irqbalance (only a path problem). I posted some info here: http://lists.digium.com/pipermail/asterisk-dev/2013-December/064182.html Let me know if you want to look at it. jg -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Look for irqbalancer for your distribution: http://www.tutorialspoint.com/unix_commands/irqbalance.htm Am 14.05.2014 09:00, schrieb Chandrakant Solanki: Hello All, I have 2 Digium card configure on Single machine, which can't share interrupt across all CPUs and sometimes asterisk reach 100% CPU usage.

Thanks for reply, I am interested to see patch, but I don't find any link for the same. -- Chandrakant Solanki On Wed, May 14, 2014 at 2:09 PM, Thorsten Göllner t...@ovm-group.com wrote: Look for irqbalancer for your distribution: http://www.tutorialspoint.com/unix_commands/irqbalance.htm Am 14.05.2014 09:00, schrieb Chandrakant Solanki: Hello All, I have 2 Digium card configure on Single machine, which can't share interrupt across all CPUs and sometimes asterisk reach 100% CPU usage.
