Sean Bright commented on ASTERISK-28422:
----------------------------------------

Thanks for the updated example.

I don’t quite understand what the goal of your example code is but a potential workaround would be to not set these values over and over again in an endless loop. You could set them once before entering the infinite loop which should at least decrease how much memory is being used. That might help hold you over until someone has time to look at the code more closely.

>      Security Level: None
>          Components: Applications/app_confbridge

>         Environment: Debian GNU/Linux 9.8 (stretch)

> 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}
