Broken Stream on Metadata Change #3234

Closed DEBIANsince99 closed 1 year ago

DEBIANsince99 commented 1 year ago

Dear friends of Liquidsoap. I use LiquidSoap along with LibreTime in a Docker container and I have the following issue when playing external webstreams. As soon as the metadata changes in the external webstream, liquidsoap interrupts the stream.

Hi @DEBIANsince99, What version of Liquidsoap are you currently using? Also, if you are using the docker-compose.yaml provided by LibreTime, what version of LibreTime are you using?

I suggest asking your question on libretime's discourse forum for better productivity. Having a complete understanding of the pipeline will enable them to identify the problem's source more quickly.

Dear Vito, I use docker. The docker environment ist running on debian 12.0, with debian docker packages.

Because of 800+ liquidsoap zombies i modified the docker-compose.yml with 'init: true ulimits: nofile: 1024', but this did not fix the problem we are talking about, neither a version change for libretime to main an icecast to 2.5-beta3.

Currently i think it you could be a problem of liquidsoap but i did not have a full understanding of the 'signal way' inside of liquidsoap yet. Regards Dominik

Liquidsoap 1.4.3 from debian 11 repo LibreTime main-bd6822fec615a2329745cf18aa3039a157870d47

800+ liquidsoap zombies

This is not ok.

Hi @DEBIANsince99. Unfortunately, due to limited resources, we are only able to support the current release cycle which, as of now, is 2.2.x. Feel free to try and update your script and we would be happy to revisit your issue.
