> Starting with Asterisk 14 and usage of ARI, memory is leaking on stasis_channels.c file. In Asterisk v13.11.2 this is not happening. After I have noticed it on version 14.2.1, I've found an open issue ASTERISK-26767 and thought this is the problem (althought I don't use channelvars in ari.conf, but I do use vars in dialplan when starting ari app) and installed 14.5 but unfortunately problem didn't dissapear so it must be something else.
> In extensions.conf I have following:
> {noformat}
> [from-iax2-server-1]
> exten => _.,1,Stasis(AriStart,TRUNK=${CHANNEL(peername)})
> {noformat}
> My ARI app originates calls to other server through IAX2 and receives calls back from the same server and channel driver. I've also tried other channel drivers SIP and PJSIP and issue was still there.
> What is obvious is when I run CLI command 'memory show summary', there is large memory allocation growth in file 'stasis_channels.c'. You can see it in attached files 'memX.txt'.
> I have enabled 'MALLOC_DEBUG' but unfortunatelly there is only one line in 'mmlog' file, and I don't understand why.
> Memory is growing until Asterisk eats all available memory and then crashes!
