[asterisk-bugs] [JIRA] (ASTERISK-28422) Potential memory Leak in Confbridge

[Ted G (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-28422?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=247249#comment-247249 ] 

Ted G commented on ASTERISK-28422:
----------------------------------

Ive done the first suggestion.  When using confbridge.conf instead (which takes many similar blocks of code to achieve what I'm doing) the memory leak goes away.

Testing individual settings is going to be very time consuming.  I would probably just go back to the confbridge.conf method instead.

Funny you're not able to reproduce this.  I was able to able to reproduce on both version 16 (current) and the official version 11.  Exact same results.

May I see your code?

> 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}
