Oops. Guess I should complete the thread...
You can set the DAHDI pseudo channel limit in /etc/modules.conf:
options dahdi max_pseudo_channels=x
or you can set it from the command line like:
echo x >/sys/module/dahdi/parameters/max_pseudo_channels
It appears you need 1 DAHDI pseudo channel per caller and 2 pseudo
channels per meetme.

To be more exact, you need one DAHDI channel of *some kind* per caller.
For DAHDI hardware channels (e.g. PRI), Meetme can mix directly from
the channel and doesn't need a pseudo too.
For VoIP channels (and a few other cases), Meetme needs to route the
call through a DAHDI pseudo channel to give it data to mix.
And yes, two pseudos per meetme - one for recording from and one for
playing announcements into the conference.
Cheers
Tony

If you have too many conferences, one CPU may not be able to mix all the
audio and you will have audio problems even if there are 7+ other CPUs
that are essentially idle while waiting for one CPU to mix everything.
You should be able to handle 512 conference participants on a modern
server system without problem. The current trunk of *DAHDI linux limits
the number of open pseudo channels to 512 for this reason*. [1]
Thanks,

I would check /proc/interrupts also. On some distros irq's are not
balanced by default and are all hitting the same core.
On Debian I had to install the irqbalance package and the load was
spread across the cores.
Dahdi is still a single thread thought.

With 312 calls distributed across 100 meetmes, 'top' shows 1 core at 32%, 1
core at 6% and the rest basically idle.
So it looks like meetme() is still a single CPU application, but I have
plenty of CPU headroom.
Coincidentally, 512 is my target. Any clues on how to get 200 more?

Steve,
If you're looking to reduce the CPU overhead of processing meetme
conferences, this email from awhile ago may be of some help:

Thanks for the clue. I can hit my target of 512 on an Intel E3-1240v3 with
'pre-packaged' Asterisk so I'm good for now.
