Survey campaign maxing out something

Postby Vince-0 » Wed Dec 13, 2017 4:48 am

Hi!

I've moved a vici server (database) to run a survey campaign from a 7.0.4 server to a 8.0.1 server

On 7.0.4 server, usually we can push a survey campaign on bare metal server with around 2527 channels / 876 concurrent calls without errors.
On 8.0.1 server, we use the same CPS, max trunk settings and campaign dial ratios and get around 500 channels/210 calls and these errors spam the asterisk warning log:

pbx.c: Failed to create new channel thread
..
tcptls.c: Unable to launch helper thread: Resource temporarily unavailable

And can't get over about 210 concurrent calls.

We've tried two different servers and sets of RAM with the same results on 8.0.1
The only difference I can tell is OS and kernel versions, Vici, Asterisk etc are the same between servers.
I am going to try re-deploy on 7.0.4 ISO and try re-create the problem and post more info.

Any advice would be greatly appreciated.

We never test capacities that high because in our experience the possibility of crashing increases dramatically the higher concurrent call volumes you go.

We always recommend scaling by adding more servers instead of trying to cram more calls into each dialer.

In our testing we use single quad-core CPU machines, and we usually don't go beyond 180 concurrent calls.

We've found in our Asterisk 13 testing that it can usually handle more call load than Asterisk 11 can.

Hi Vince-0, I'm facing the same limitation on 8.0.1. Have you got your issue resolve?

We did a lot of testing of FreeSwitch a few years ago, it has it's own issues... :)
