Hi everyone,
I was using the previous version of SIPp(3.1) for a simple stress-test
scenario, sending about 5000 SIP INVITE messages per second to my SIP
server with a command
./sipp -sn uac thorserver:5060 -sf myreg.xml -inf users.test -m 25000 -r 5000
and everything worked just fine (myreg.xml is just a simple register
scenario derived from the examples, attached).
Nowadays I am playing with a simple load balance scenario and I wanted
to use the same scenario sending the messages to more different
servers(and avoid running more instances of SIPp). I have found a
setdest action that works just fine for my purpose, however it is only
in the newer version (SIPp 3.2). I have adapted the scenario and run
it, yet no messages have been sent. When I run the old
scenario(without any changes), it does not work either(it does not
even send a single message). When I decrease the -r parameter and set
it to 1000 or under, everything works ok. Once I set it to 1001 or
higher, not a single message is generated.
Funny thing is that when I manually increase the number of messages
during the simulation (using + or *), it works and SIPp is sending
more than 1000 messages per second.
Is there any new limit set somewhere in the new version of SIPp? Any
ideas where the problem might be? (The previous, 3.1 version works
just fine, however it does not support the setdest command which I
would like to use).
Thanks,
John
