I have same problem (ububtu 22.04), i cannot debuging what causing the problem. For me, it can stop when the stream is not .mp3 and the broadcast close sometimes. I tried many versions but i don't know why crashing.

We also have backup mount points, aac+ format. But both the backup points and the original ones are absolutely identical in format and other parameters. We still cannot understand that this is the reason. Karl needs help! ))

sorry for not getting back sooner, had non-icecast issues to deal with. Obviously need to know where the hang is in such cases, do make clean debug and run to get a hang case. Then use gcore to grab a core file which can be inspected

The point is that it is impossible to understand when an icecast crash will occur. This can happen every day or every 3-5 days. If you enable debug logs, will the data be displayed or not? How to gcore?

The only thing we noticed was a problem with determining the aacp format. For example, we receive an aacp stream from another server. If you do not specify the type, aacp is automatically displayed. However, if the current icecast relays the stream, then it itself produces the aac type. As I understand it, aac and aacp are different formats and perhaps this is the problem.

Hi Karl,
Just got this crash on a test server. mount point has no auth. Mount point in an on-demand relay (with multiple relays).
I'm currently trying with on-demand=0 instead of 1, it seem more stable.
I cant reproduce the crash manualy, i need to put the server in "test-production" to crash it.
Best
