High RAM Usage; Ram Usage increase all the time

[tausday]

Describe the bug
Hello i have a clear install srs from stock. After 6H runtime without Clients and Streams i have a ram Usage from21% from 2GB.
On Older test i see an idle ram usage of 23MB not 420MB like me

If i kill the prozess with pkill srs it slowly increase ram usage from 2,1%. After 1 Minute i have 3.2% in idle

Version
SRS/7.0.20

To Reproduce
Steps to reproduce the behavior:

1. I Start the server with: ./objs/srs -c conf/srs.conf
2. Whaitt a time and the ram usage increase without streams and clients.

My Config looks like:

listen              1935;
max_connections     1000;
#srs_log_tank        file;
#srs_log_file        ./objs/srs.log;
daemon              on;
http_api {
    enabled         on;
    listen          1985;
}
http_server {
    enabled         on;
    listen          8080;
    dir             ./objs/nginx/html;
}
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__ {
    hls {
        enabled         on;
    }
    http_remux {
        enabled     on;
        mount       [vhost]/[app]/[stream].flv;
    }
    rtc {
        enabled     on;
        # @see https://ossrs.net/lts/zh-cn/docs/v4/doc/webrtc#rtmp-to-rtc
        rtmp_to_rtc off;
        # @see https://ossrs.net/lts/zh-cn/docs/v4/doc/webrtc#rtc-to-rtmp
        rtc_to_rtmp off;
    }

    play{
        gop_cache_max_frames 2500;
    }
}

Hello, today i have push a test stream to osr with ffmpeg and 1 client.. now i have no clients an no users but osrs use now 50,9% of ram form 2GB

There might be a memory leak with HLS components.Try disable that.

hy,

i habe changed

hls {
enabled off;

to off and restart it, no changes in ram usage

[tausday]

Hy I have test it from 5.0 over 6.0 to developer releases all the same

If I refresh the summary/dashboard often I can see a ram usage increase faster than I do nothing.

Maybe some log files in cache or other thinks in cache?

Any ideas. I don't can be the first who find out it :)

flv is the same

max_connections 65535;
daemon on;
pid ./pid/srs_origin_1.pid;

srs_log_file ./logs/srs_origin_1.log;
srs_log_tank file;
srs_log_level info;
inotify_auto_reload on;

http_api {
enabled on;
listen 9881;
}
http_server {
enabled on;
listen 9281;
dir ./objs/nginx/html;
}
vhost defaultVhost {

origin_cluster on;
coworkers 10.32.37.254:9882 10.33.36.10:9881 10.33.36.10:9882;
}

publish {
    normal_timeout 5000;
}
http_hooks {
    enabled         on;
    on_dvr          http://127.0.0.1:8089/api/v1/live;
}

dvr {

}

}

This issue has been resolved in the latest version of SRS 6 and SRS 7.

Root Cause: Address Sanitizer (ASAN) was enabled by default in version 7.0.20, which caused significant memory overhead and apparent memory growth. ASAN is a debugging tool that intentionally holds onto freed memory to detect use-after-free bugs, which explains why RAM usage kept increasing even when idle.

Solution: Sanitizer has been disabled by default in newer versions. Please upgrade to the latest SRS version to resolve this issue.

If you're unable to upgrade immediately, you can rebuild SRS from source without the sanitizer flag as a workaround.

The expected idle RAM usage of ~23MB (without sanitizer) is normal for production builds.
