>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Functions/General
>    Affects Versions: 18.13.0, 18.15.0
>         Environment: Centos 7, alpine
>            Reporter: David Uczen
>            Severity: Critical
>
> Calls to JSON_DECODE appear to be leaking memory. The more this function is called and/or the larger the size of the json being parsed the worse the leak appears to be.  
> We started using this function to parse some call routing data from a json api and have been seeing servers quickly run out of memory. The memory increases in line with call volume and is not recovered. We wrote some test dialplan (see attached) that parses json in a loop to reproduce the issue and can confirm it exists in both 18.13.0 and 18.15.0 we compiled ourselves on centos as well as the packaged version that exists in alpine:latest (18.13.0).
> Note: Functions/json_decode is not available in the dropdown for 'Components' at the time of issue creation.
