Hello,
we are curently benchmarking an asterisk system
1034 sip users are logged into this system and the test software is
trying to establish 400 concurrent calls.
In the CLI I see the following messages:

I have set "fs.file-max = 65535"in /etc/sysctl.conf and in
/etc/security/limit.conf (according to the wiki):
asterisk soft nofile 65535
asterisk hard nofile 65535
What more can I do to increase the number of open files?
Is it possible to see how many files asterisk uses and how many files it
needs?
Thanks for your help,
Stefan
Stefan,
Take a look at this post:
http://lists.digium.com/pipermail/asterisk-users/2006-April/147204.html
Additionally, are you running Asterisk as the user "asterisk" or as
"root"? If you are running Asterisk as "root", you'll want to change
your entries in limits.conf to reflect that as follows:
root soft nofile 65535
root hard nofile 65535
I'm also interested in large-scale single server setups. We have one of
our own in production now. During our scalability testing, we used an
Abacus 5000 to digitally record 512 simultaneous SIP-to-SIP calls on the
system.
Would you please post the hardware you are running Asterisk on, your
configuration (with a focus on scalability optimizations and tweaks),
and your testing methods? I'd be glad to share information with you to
help you achieve your goal.
Thank you,
