hi i have a query I can't find the answer to. One of my miners (on the eu server) keeps telling me

"accepted untracked stratum share from pool 0"

I'm using cgminer 3.7.2, and not using --no-submit-stale

The other miners (also pointing to the eu server) don't, which confuses me since this link (below) suggests it is to do with the server.

but that doesn't make any sense, because only one of my miners is doing this and all my miners are pointing to the same server..

Is there something obvious I'm missing ??
