Thanks for the detailed feedback.

I'm not seeing the same memory differentials on my machine. Could you try the same scenario, but without any "ast_setvar" commands to set up the conference? If the memory issue does not seem to be present after that, can you try testing with individual settings (i.e., music_on_hold_when_empty, mute, etc.) and provide results to see if you can single out a setting or if it's all CONFBRIDGE settings?

>      Security Level: None
>          Components: Applications/app_confbridge
>    Affects Versions: 16.3.0
>         Environment: Debian GNU/Linux 9.8 (stretch)
> Using AGI

> When users on my system join a conference bridge some variables are being set dynamically like so:
> {noformat}
> 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");
> {noformat}
> 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:
> {noformat}
>    54616804 bytes in      15255 allocations in file confbridge/conf_config_parser.c
> {noformat}
