>                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25022
>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Core/RTP, Resources/res_rtp_asterisk
>    Affects Versions: 11.17.1
>         Environment: Load testing using JsSIP over WebSockets
>            Reporter: Steve Davies
>
> Load testing of inbound call over WebSockets using JsSIP, routed out over a regular SIP call. Calls started at 0.5s intervals and allowed to run for 10s.
> After a period of time, a memory leak was apparent. Using DEBUG_ALLOC and REF_DEBUG found the following issues:
> ==== Leaked Object 0xb2820c54 history ====
> [22433] res_srtp.c:240 ast_srtp_policy_alloc: +1 Allocating policy - [**constructor**]
> [22433] res_srtp.c:516 ast_srtp_add_stream: +1 Added additional stream - [1]
> [22078] res_srtp.c:480 ast_srtp_destroy: -1 Unallocate policy - [2]
> --
> ==== Leaked Object 0xb31868fc history ====
> [22449] res_srtp.c:240 ast_srtp_policy_alloc: +1 Allocating policy - [**constructor**]
> [22449] res_srtp.c:461 ast_srtp_create: +1 Created initial policy - [1]
> [22078] res_srtp.c:480 ast_srtp_destroy: -1 Unallocate policy - [2]
> And using 'uniq -c' on memory allocations output the following entries were never free'd:
>    1126         31 bytes allocated by ast_rtp_dtls_cfg_copy() line  2295 of rtp_engine.c
>    1126         33 bytes allocated by ast_rtp_dtls_cfg_copy() line  2296 of rtp_engine.c
>    1126          8 bytes allocated by ast_rtp_dtls_cfg_copy() line  2297 of rtp_engine.c
