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:

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
0 session(s) per Sec out of max 400, peak 164, last 5min 8
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
Limit Soft Limit Hard Limit Units
Max cpu time unlimited unlimited seconds
Max file size unlimited unlimited bytes
Max data size unlimited unlimited bytes
Max stack size 245760 8388608 bytes
Max core file size unlimited unlimited bytes

Max pending signals 62815 62815 signals
Max msgqueue size 819200 819200 bytes

Any idea? Thanks.

Igor.
