Source: The memory leak seems still exist

[tonyye2018]

The memory issue with SRS still appears to persist. I use RTMP to push streams to SRS, and then play them using WebRTC. After playing for a while, I close the stream, then push and play again, only to close it once more.
Version: 6.0 develop branch 2024.6.18
this is my test result:
unit is KB
Startup memory: SRS 19032.

What's your SRS config?

[tonyye2018]

I use the rtmp2rtc.conf or srs.conf which enable rtmp_to_rtc.

http_server {
    enabled         on;
    listen          8080;
    dir             ./objs/nginx/html;
}

http_api {
    enabled         on;
    listen          1985;
}
stats {
    network         0;
}
rtc_server {
    enabled on;
    listen 8000; # UDP port
    # @see https://ossrs.net/lts/zh-cn/docs/v4/doc/webrtc#config-candidate
    candidate $CANDIDATE;
}

vhost __defaultVhost__ {
    rtc {
        enabled     on;
        # @see https://ossrs.net/lts/zh-cn/docs/v4/doc/webrtc#rtmp-to-rtc
        rtmp_to_rtc on;
        # @see https://ossrs.net/lts/zh-cn/docs/v4/doc/webrtc#rtc-to-rtmp
        rtc_to_rtmp on;
    }
    http_remux {
        enabled     on;
        mount       [vhost]/[app]/[stream].flv;
    }
}

        rtc_to_rtmp off;

I use the version which you merged newest code on morning.
I get the same result.From the srs.log, I found "free rtc source id=[4t2o11ll]", it seems rtc source had been freed.
But the memory is still growing.

Memory growth does not necessarily indicate a leak; it could be due to system caching, among other things. You can conduct tests for over an hour, and if the increase persists, then it is likely a leak.
