Re: [asterisk-dev] IAX2 changes - thank you!

In our production systems we don't use registration, all clients call in, no calls go out. As a consequence, our stress tests are designed to simulate that. So it looks like there are some code paths that we have not covered and might still have some issues ...

Hello,
for now I did some basic testing. So I flooded asterisk with 800
registrations, one every millisecond. Yep, this is a lot but no problem
for SIP at all. It works for IAX too as long as "rtcachefriends=no".

Because I like being nice with asterisk I even try to reload asterisk
during the flood process. Everything works fine except if
rtcachefriends=yes. In that case I need to wait only a few seconds and
asterisk crashes. This problem is in asterisk since always.

The last thing I see on my CLI  is:
*** glibc detected *** corrupted double-linked list: 0x0000002a9e649f40
***
Aborted
If anyone is interested in core dumps just tell me. I can also give root access to a test box with with the flood tool etc... This might speed up
things as the test environment is ready.

We are running asterisk on DELL 1850 servers and Redhat Enterprise
Linux. Mysql is on a different box but on the same lan. We use ODBC to
connect to the mysql server.
Now, I know that those tests are not really an everyday situation. This is why I will try to put it in production on Monday and provide further
test results.

Best regards,
Loic Didelot.

I look forward to your results.  I love the concept of IAX but in
production it was a real headache and actually unusable for anything
critical.

Thanks,
Steve

We have around 500 users online using iaxclient. I will deploy the new
version in the next days and provide feedback.
I will also do my usual stress tests to check how things have improved. Ususally when I stess IAX asterisk crashes. So lets check what I got in
a few days.

Best regards,
Loic Didelot.

Are the mentioned recent fixes in 1.4 or just in trunk?
Both
I remember not too long ago there was discussion about IAX under
1.4 not
being robust and sometimes locking up. Has this been resolved now?
Hopefully :)
We could use more testing though, so if you use IAX2 in your systems,
we'd be happy to hear your results...
