[OpenSIPS-Users] OpenSIPs Stress test problem

[Luis Morales]

The script is simply forwarding requests and responses in a stateless manner. I've tried the simple stateful configuration in the opensips site, but I've like to try it with the stateless configuration. Here's the script I'm using:


####### Global Parameters #########
debug=0log_stderror=no
fork=yeschildren=12
/* uncomment the next line to disable TCP (default on) */disable_tcp=yes
#listen=udp:10.0.0.1:5060port=5060


####### Modules Section ########
#set module pathmpath="/usr/lib/opensips/modules/"
loadmodule "sl.so"loadmodule "tm.so"
modparam("tm", "wt_timer", 2)modparam("tm", "restart_fr_on_each_reply", 0)# ----------------- setting module-specific parameters ---------------

####### Routing Logic ########

# main request routing logic
route{	forward();} 

The errors I'm receiving in sipp are like the following:
2011-09-11	19:42:41:161	1315784561.161207: Aborting call on unexpected message for Call-Id '188-8326@::1': while expecting '200' (index 5), received 'SIP/2.0 180 RingingVia: SIP/2.0/UDP [::1]:5062;received=127.0.0.1;branch=z9hG4bK-8326-188-0From: sipp <sip:sipp@[::1]:5062>;tag=8326SIPpTag00188To: sut <sip:service at 127.0.0.1:5061>;tag=188Call-ID: 188-8326@::1CSeq: 1 INVITEContact: <sip:[::1]:5061;transport=UDP>Content-Length: 0

Can't really tell without seeing what the errors are and what your script is doing. Are you doing any database lookups??

Hello Brett,
You're right, I forgot to check the logging. I disabled it and it's working better. I'm still getting some unexpected messages error, but a lot less than I was getting before. Thanks for your help. Do you know if there's something else I could do so I could stop getting the errors.?



Thanks,
Luis Morales.

I'm using version 3.1 and I've also tried version 3.2 and I have the same problem in both. I used the -trace_err to see what the errors where, and the problem is that while Sipp is expecting a particular response, it receives another, for example, while expecting and acknowledge it receives an OK. I used wireshark to see what was happening, and i saw that the Opensips server introduces a little delay  in sending each response, but what I don't understand is why with such a small call rate I'm having this problem.




Luis,
You didn't answer my logging questions. I've seen bad logging configurations totally disable an opensips server. Specifically a registration server that could handle ONE phone but not TWO. No kidding. Problem was 100% syslog setup. Disabled logging and back up to being able to handle thousands of phones. 




This is pretty well documented and has been reported in the past. That may be your issue.
