Description

v6.0.22 code, after compiling with Docker, it was noticed that certain pods had restart records after running for a while. Upon checking the logs, there were error records indicating heap_buffer_overflow, which is a memory overflow issue.

Docker compilation command

docker build -t srs:v6.0.22 --build-arg CONFARGS='--with-transcode  --http-callback=on --ssl=on --hls=on --http-api=on --stat=on --http-server=on --ffmpeg-tool=on'  --build-arg INSTALLDEPENDS='YES'  --platform linux/amd64  -f trunk/Dockerfile  .

Replay

Please describe how to replay the bug?

Step 1: docker image build

docker build -t srs:v6.0.22 --build-arg CONFARGS='--with-transcode  --http-callback=on --ssl=on --hls=on --http-api=on --stat=on --http-server=on --ffmpeg-tool=on'  --build-arg INSTALLDEPENDS='YES'  --platform linux/amd64  -f trunk/Dockerfile  .

Step 2: docker run and push rtmp stream

1. Deploy the compiled image and run it.
2. After running for a certain period of time, some pods crash and restart. The specific reason for this issue is currently unknown.

Expect

No memory overflow crash issue during normal operation.

asan's stack is too small, why is there no complete stack? Can you check if there are any other logs available?

If not, the only option is to map the core file and check the stack.

Last week, I observed for a week but still couldn't find a way to reproduce it. The logs before the crash only have the logs recorded above. How is the core file mapped out?

I also encountered the same problem. Use case: pushing the stream in RTMP protocol, converting it to WebRTC protocol through RTMP, and reproducing the problem after running for more than ten hours, as shown in the figure:
Enterprise WeChat Screenshot_16774606903458
The key stack log is as follows: [File: srs.log]

Just to add to the phenomenon of xiangzi1: when playing 27 videos through WebRTC on the browser, there is a continuous increase in memory usage in SRS. Every 30 seconds, it stops and then resumes playing. After running for more than ten hours, it eventually crashes with the error "heap-use-after-free". This issue was discovered in version V5.0.141@winlinvip.

During the htp_hook_on_play period, the rtc connection timed out and was deleted, resulting in the use of a wild pointer.

@limjoe Please ask a question. I noticed that when you start Docker, SRS logs are printed to the console. I remember that after the container restarts, the logs cannot be found, right? I wonder how you find the logs of previous containers? Do you record the container ID?

@winlinvip In k8s, using the command "kubectl logs -f origin-rtmp-cluster-1 --tail=100 -p" allows you to view the logs before the container crashes.

@limjoe, can you make this log above more complete? Or you can stop logging to the console and directly output it to a file.
