David Hajek commented on ASTERISK-27261:
----------------------------------------
We can see similar json.c leaking on lastest asterisk 13.17.0. The problem seems to be with every request which contains content-type: application/json. We even tried latest 2.10 jansson library with the same results.
This is how 'memory show allocations' looks after several API requests (eg. call originate).

> I am running a program that do use ARI to originate calls and also receive calls through SIP into a stasis application , I noticed that almost every 3 days i got my 6 GB server memory full . I first thought it is from moh but then after checking the memory i noticed that stasis_channels.c is getting increased all the time , i did a restart and tested with only one call and i noticed that on each call the number of allocation increased by 2 (while the call is active it increase by 8 then drop 6 and keep 2)
