it would, yes.

I think that there is enough hardware: 8GB of RAM and 8x2Ghz.
 
But before the error, freeswitch user was limited by OS to open 1024 files only. Is this can cause FS to lower the max session?

if you are hitting that error… the answer is likely to upgrade your hardware to have enough to actually handle those limits, or else it will just lower itself again when it hits the same error next time

Hi Michael,
 
Thanks for your response.
Indeed, I find this:
freeswitch.log.2016-12-05-11-24-27.1:Artoo reduces the max sessions to 973 thus, saving the switch from certain doom.
 
It was last Monday when I decided to modify the limits.conf.
 
So, what I can do to back on 4000 sessions max as defined in the switchs.conf? 
 
Regards,
 
Igor.

was probably the default 1000, then when hit with a big peak the box couldn't handle, it failed to create some threads, causing freeswitch to automatically lower the limit to better match what the box is capable of handling.  if you grep the logs for 973 you'll see a log where it's lowered.

Hello,
 
During some call peaks, FS replies with 503 Maximum Calls and produces the following log:
 
/var/log/freeswitch/freeswitch.log.2016-12-12-10-20-33.1:2016-12-12 10:08:54.964919 [CRIT] switch_core_session.c:2270 Over Session Limit! 973

I dig into the configuration to change many settings related to this error. So, our current "status" is:
 
FreeSWITCH (Version 1.6.5 git 70b8c17 2015-11-20 20:57:50Z 64bit) is ready
1207363 session(s) since startup
684 session(s) - peak 983, last 5min 694

973 session(s) max
min idle cpu 0.00/39.77
Current Stack Size/Max 240K/8192K
 
I don't understand how the 973 sessions max is determined? The switch.conf.xml is set as follow:
 
  <settings>
    <param name="colorize-console" value="true"/>
 
    <param name="dialplan-timestamps" value="false"/>
 
    <param name="max-db-handles" value="50"/>
    <param name="db-handle-timeout" value="10"/>
 
    <param name="max-sessions" value="4000"/>
    <param name="sessions-per-second" value="400"/>
    <param name="loglevel" value="debug"/>
 
    <param name="mailer-app" value="sendmail"/>
    <param name="mailer-app-args" value="-t"/>
    <param name="dump-cores" value="yes"/>
 
    <param name="rtp-enable-zrtp" value="false"/>
 
    <param name="min-idle-cpu" value="0"/>
    <param name="enable-clock-nanosleep" value="true"/>
 
  </settings>
 
I also made modifications to the OS himself, into limits.conf:
 
freeswitch       hard    nofile          500000
freeswitch       soft    nofile          500000
freeswitch       hard    nproc           62815
freeswitch       soft    nproc           62815
 
The setup looks to be active:
 
# cat /proc/25695/limits
