pbxnsip CPU Limit

[Sub-Zero]

We are running pbxnsip on a Intel Core 2 duo 3.0ghz 2m cache 2gb ram, the pbx can only run on one of the cpu's. Is there a setting that we can change so that both cores can be used? Or any suggestions how to improve the pbx performance on the box?

 

Our error sent by pbx as follows,

 

CPU meter shows 76, which is over the threshold of 75. Therefore, a new call has been rejected

First I'm curious how many extensions on this system? ;-)

(just curious)

 

Yes, you can run pbxnsip twice on the same server...but it is two pbxnsip's then.

Running the process on several cores is not possible. We tried, but this resulted in jitter in the 50 ms area which is not okay. Seems like the OS needs to put the whole process on hold (MMU) when creating a new thread that affects another core.

 

What you could do is run two instances of the PBX in seperate folders and cores. This is like running two seperate PBX. The disadvantage is that you also need to maintain two PBX. If you are operating a server farm with many PBX and domains anyway, that should be easy. However if you just have one domain, this will be quite a big step.

 

After all, it is a PBX, not a class 4 switch.

Hello,

 

I have the same problem. I received an email that read "CPU Limit", "CPU meter shows 51, which is over the threshold of 50. Therefore a new call has been rejected". Can I increase from 50 to 75 or higher and how would I be able to do this?

Yes you can... Check http://kiwi.pbxnsip.com/index.php/Global_Configuration_File for the limit. IMHO 50 is a good value especially for smaller systems. For systems with a lot of calls, it is okay to increase it to something lik e75; but never go to 100.
