[asterisk-app-dev] Problem when load testing Asterisk 13.7.2

Sat Mar 19 21:29:48 CDT 2016

Thanks again, George,

I am running PJSIP v. 2.4.5 that is prescribed for Asterisk 13.7.2. I made
the changes you proposed re: --enable-epoll, recompiled PJSIP/Asterisk and
redid the tests.

I am attempting a total of 100 or so connections (50 SIP/TCP callers
REGISTERing, INVITEing; 50 SIP/TCP callees REGISTERing, accepting calls). I
am afraid the latest Asterisk is not something I can try right now.

I am left now with an issue that I have not been able to get help elsewhere
re: SIPp. I hope I can ask them here, but if I can't, I am sorry in advance!

I get these errors:

Unable to bind audio RTP socket (IP=127.0.0.1, port=6100), errno = 98
(Address already in use). (also get the same error but with video RTP
socket, but I am NOT running any video tests).

OR

Unable to bind main socket, errno = 98 (Address already in use).

OR

Unable to bind remote control socket (tried UDP ports 8888-8947): Address
already in use. (no idea what this is, and why this occurs)

I tried passing the -mp parameter (for sipp, i.e.,) a random port number
(e.g., see
http://stackoverflow.com/questions/2556190/random-number-from-a-range-in-a-bash-script)
but I still get these issues (though they dramatically decreased the number
of issues I see due to port number).

Apart from ulimit/FD_SETSIZE related changes, what else can I do?

Where can I get information about load testing Asterisk for more than 100
concurrent calls (I use ARI, so I have to test my backend application too)
etc.?

Thanks!
