Greetings......
I'm attempting to add a 3rd stream on my local network. It functions fine with 2streams , but when I add a 3rd stream I get an error. I'm using op25 with Icecast and liquidsoap. The hardware is a NUC with an i5-8259u, quad core, 2.30ghz, 16 gb ram. All of the syntax appears correct and permissions seem correct. I'm stumped. Suggestions ?
Here is my op25.liq script:
Here is the pertinent part of the error message from op25.liq
And here's my executable start-up script
