Good morning,

as nobody else jumped in, let me try to figure it out. :)

POKE-requests are part of libshout performing detection of sever
features and bugs. This is for compatibility with both very old Icecast
servers or when for example talking to some other software that never
implemented everything.

I'm not sure about this part. My guess is that you talk to ICY metadata
updates in the legacy format support. From having a quick look at the
code, it might be true that libshout does a POKE here for every update.

This is something related to libshout's implementation. So an update on
that might have changed things. Also keep in mind that this is purely
source client side, so this doesn't depend on the Icecast or it's
config at all.

So generally speaking this is totally fine to happen. And not a problem
at all. No actions required.
If in fact it does this for every update in the legacy code path that
is a bit unfortunate. Maybe we can have a look at that and see if we
can cache the result. But beside an error.log entry there is no harm to

Hope that helped! :)
