That does not matter.
On Linux, I get results with 50 calls per second, every call continues for 24 seconds, 1000 concurrent calls, and 10 000 total calls with only 3 failed calls. Tested kazoo cluster, more complex cluster then standalone freeswitch.
So must work on Linux

SIPP can record failed call ID
Using this call-id you search for FreeSwitch logs.
Also, you can record all network traffic using dumpcap or tcpdump utility to disk. Later you can open these pcap files using sngrep utility and check waht is wrong with failed calls.

Hello,

What is your OS? What is your Sofia configuration?

What the vmstat -w -S M 1 10 says?

Can you try without Docker?

Hello all,

Let's assume i have a 28 CPU (56 cores) with 64gb RAM.
I'm load-testing that box with something like this:

SIPp->--\       /----> FS1
         ---->FS
SIPp->--/       \----> FS2

SIPp is simply sending calls with rtp to FS.
FS just forward the calls to FS1 and FS2 based on some very simple decision.
FS1 and FS2 simply answer and execute echo.
At ~2000 channels FS fails to reply to some SIP messages, basically calls are timing out, answer ratio goes down.
BUT CPU never goes over 45% on the FS and memory is ample. I don't see packe drops on the interface. 
FS is running in a docker.

I'm wondering whether FS would use all of the available CPU or am I hitting some other limit somewhere.

Any insight is welcomed!
