That would be the PJSIP memory pool, which can make things extremely difficult to track down.

Can you narrow it down further? What's an example configuration that exhibits it? Are you doing reloads often? Are there calls going on?

>          Issue Type: Bug
>      Security Level: None
>          Components: Core/General
>    Affects Versions: 16.4.0, 16.4.1, 16.5.0
>         Environment: Asterisk 16.5.0, OpenBSD 6.6-beta
>            Reporter: Mark

> After updating OpenBSD 6.6-current about 4 weeks ago, i've also
> updated Asterisk 16.4.0 -> 16.4.1. Since then, Asterisk started 
> using more and more memory. Right now, i'm running Asterisk 
> 16.5.0 and OpenBSD 6.6-beta in a very small test environment and 
> i still see the same issue.
> Weeks ago, Asterisk started with ~60MB and stayed around that 
> value...now it starts with ~60MB and increases by 80MB/24h 
> without any calls made.
> After compiling with MALLOC_DEBUG and running "memory show 
> summary" every few hours, there's only one line that goes through 
> the roof:
> * after start
>  5542784 bytes in        464 allocations in file ../src/pj/pool_policy_malloc.c
> * 12h later
> 67805312 bytes in      25962 allocations in file ../src/pj/pool_policy_malloc.c
> The same applies for "memory show allocations":
> * after start
> $ grep "pool_policy_malloc.c" allocations_start | wc -l
> 468
> * 12h later
> $ grep "pool_policy_malloc.c" allocations_12h | wc -l
> 25968
> The only setting that stops Asterisk from allocating more and more
>  memory is, when removing "registration" and "endpoints" from
>  pjsip.conf. This way, Asterisk only listens on 5061 TLS and does 
> nothing.
