             Summary: Potential memory Leak in Confbridge
                 Key: ASTERISK-28422
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-28422
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Applications/app_confbridge
    Affects Versions: 16.3.0
         Environment: Debian GNU/Linux 9.8 (stretch)
Using AGI
            Reporter: Ted G
            Severity: Minor


When users on my system join a conference bridge some variables are being set dynamically like so:

ast_setvar("CONFBRIDGE(bridge,record_file)", recfn);
ast_setvar("CONFBRIDGE(user,startmuted)", mute ? "yes" : "no");
ast_setvar("CONFBRIDGE(user,music_on_hold_class)", music ? music : "default");
ast_setvar("CONFBRIDGE(user,music_on_hold_when_empty)", music ? "yes" : "no");

All of this works fine, however users are quite often taken off the bridge to change these settings so every time they enter the bridge these settings are applied based on whatever configuration they are using.

My assumption is that once the channel is destroyed (upon Hangup) these settings vanish.  I am not using confbridge.conf at all.

My assumption appears false however as memory usage continues to grow day by day:

   54616804 bytes in      15255 allocations in file confbridge/conf_config_parser.c
