As per my standard practice when upgrading from one version to another, I rebuilt the cache.

However, When I try to either rebuild the cache or refresh the cache, I keep getting the following unexplained warnings (which given the paucity of the populated cache, I suspect they might be errors).

Not sure where the problem lies. No obvious connectivity problems with either the BBC website or the internet generally and although Scotland is a bit of an odd place, still within the UK.

Any ideas where I'm going wrong?

Follow our instructions to provide a proper report so we can see what is happening on your system. You can kill get_iplayer after 5-6 warnings to avoid too much spew. The fact that this happens on so few schedule pages (and different pages in different invocations) points to connectivity or server problems. My guess is that those pages were truncated upstream, so there was little or no information to parse.
