-----------------------------------------------------------

Update: My last tests show, that it's definitely not related to the local OpenSSL/LibreSSL version, but the changes between bundled pjproject 2.8<->2.9. (as hinted by Michael) To be more precise, the following library makes the difference:

libasteriskpj.so.0.0

When running Asterisk with libasteriskpj.so.0.0 coming with Asterisk 16.4.0 (pjproject 2.8) everything's fine. It doesn't matter if you're running Asterisk 16.4.* or 16.5.*
As soon as i copy the libasteriskpj.so.0.0 from Asterisk 16.5.1 (pjproject 2.9), the memory issue starts.

>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Resources/res_pjsip, Resources/res_pjsip_outbound_registration
>    Affects Versions: 16.4.0, 16.4.1, 16.5.0
>         Environment: Asterisk 16.5.0, OpenBSD 6.6-beta
>            Reporter: Mark
>              Labels: pjsip
>         Attachments: pjsip.ast2.conf, pjsip.conf, pjsip.conf, summary_12h, summary_start

> 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.
