Stefan Ruf commented on ASTERISK-29071:
---------------------------------------

attached files ...20200914... where asterisk restarts, after lack of memory.

=> memory short time after start of asterisk and 30 channels in use:
Mon Sep 14 10:59:39 CEST 2020
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
asterisk 21366 13.4  3.5 2796292 290024 ?      Ssl  10:26   4:25 /usr/sbin/asterisk -f -C /etc/asteris

=> memory before self-restart of asterisk:
Mon Sep 14 13:26:09 CEST 2020
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
asterisk 21366 18.0 86.9 8731732 7099416 ?     Ssl  10:26  32:20 /usr/sbin/asterisk -f -C /etc/asteris

=> asterisk restart, after "lack of memory"
[Sep 14 13:37:24] Asterisk 16.13.0 built by root @ svast20 on a x86_64 running Linux on 2020-09-08 10:04:07 UTC
...

After playing with the dialplan it seems that "Set(JITTERBUFFER...)" causes the problem.

Please tell me, is this description helpful for you ?

> Using ConfbridgeMute / ConfbridgeUnMute over AMI and additionally MuteAudio on/off results in increasing values of frame.c - shown by "memory show summary". The values rises constant over time and channel. So a system with 24 GB RAM using 5 confbridges permanent with about 20 channels each ist filled up within a day and asterisk restarts.
> The problem ist reprorduceable and starts at a certain point. This point is action-id 1705904476_335#berta-ddab9ea6-dcb4-4e83-b9bf-ff5e44325110.
> At action-id 1705904476_336#berta-67e059f6-fa67-4d4a-a73a-d5fbd4cf6475 the value frame.c increases with double speed per time. Please see attached file <ami_commands.txt>. 
> Asterisk had been compiled with MALLOC_DEBUG and “cache_media_frames = no” in asterisk.conf
> For one channel the value increases about 32 per second; for two channels the value increases about 64 per second.
> Tested versions of asterisk are 16.13.0, 16.8-cert3, 13.36.0, 13.21-cert6, all of them with the described behaviour.
