Hi,
I shall take a look at the logs then.
However, if I understand it correctly, Liquidsoap is already supposed to launch
one instance per script.
So if that's the case, when using multiple scripts, more instances are started
automatically (one per script) and distributed across the cores. Right?
Anyway, thanks for your help.
I'll check out the logs and you'll hear from me again.
