RE: [reSIProcate] Load Testing Using Resiprocate

Title: Message

Some clarifying questions:

 - are you using dum or just resip?

 - which version are you running?

 - do you have a stack trace?

 - have you run your code under valgrind to look for memory corruption?

 - do you mean 10 call setups/second per user (1000/second) or just 10/second overall spread over 100 users?

 

I have tested my B2BUA under loads of up to 60 calls/second on a dual Xeon LINUX system. In fact, I actually

ran 3 instances of my program on this machine, each at 50 calls/second with a load balancer in front of them.

So I had a total load of 150 CSPS on the system.  We split the program up only to have less calls affected

by a software failure.  This configuration ran for several days with over 10 million calls.  I never even had any

swapping and ran all within just over 1GB of physical memory (2 GB on the system).  My system is built with

0.9.0-5019.  However, I am not using dum, so I cannot comment on that part of the software.

 

Before I achieved that stability I also had crashes similar to what you describe.  It was almost always in the

stack, but I was pretty sure I was stomping on the stack.  Sure enough, I used valgrind to find that I was

writing to released memory.  Since resip uses the heap intensely and my application only uses it rarely,

resip was the most likely victim of my defects.

Hi All,

 

    Over the past one week I am trying to get my B2BUA using the resip put under load test. There are

some issues  I am seeing with the memory creeping up slowly and slowly.

 

    My team is still trying to find out is it our UAS / UAC state machines that is slowly eating up the

memory. Meanwhile I thought I will write in this mail and seek suggestions/information from you guys

on past observed behavior of Resip under load testings.

 

    We have a tool generatting load at 10 calls per second for 100 users... each call cycle being defined by

INVITE, 100 trying, 180 ringing, 200 Ok, ACK, ( Pause ), BYE, ACK.

 

    The B2BUA is running in a Linux machine and we monitor the memory using "top" command

and I see memory rising .1% to .5 % after each batch of 100 calls. Eventually after 12,000 calls

the system crashes !

 

    I wanted to ask the forum that do we have any statistics on RESIP being tested under high

traffic for long periods ? And has any kind of memory leak testing being done on Resip. Can

somebody suggest me some good tools ?

 

    Any help will be appreciated.

 

-cheers

Asheesh
