1000 threads is not really a show stopper =DThat is what the artoo message, it tells you that the new current thread limit has been auto detected and that is the new max calls you can handle henceforth.On Tue, Dec 15, 2015 at 5:16 AM, Michael Giagnocavo <mgg@giagnocavo.net> wrote:Perhaps write a patch to detect these limits and then CRIT on start if they conflict with settings.

Hey guys,
Anthony was correct in this case, I ran freeswitch not from root, for some reason my /etc/security/limits.conf file line:* soft nproc 32768
* hard nproc 32768
was not propagated on freeswitch user...
Added new line:freeswitch soft nproc 32768
freeswitch hard nproc 32768
and it worked fine from that.
Thanks to you all!

Are you running FS as root or a regular user, you need to check the ulimits of concurrent threads and some boxes have a hard limit of threads, its not all tied to CPU usage.

This post
http://unix.stackexchange.com/questions/47595/linux-max-threads-count
has a simple program to check out how many threads can be created. You
can run the test program as root and then as FS user and see if it's a
ulimit type of problem.
