Thanks for the response. Even when I have N number of indexers it doesn't work (even though the cluster is green and indexing), but I tried your suggestion anyway - still doesn't work however.
[edit]: Hmm, perhaps I stand corrected - the events no longer seem to be occurring in the logs, but I still can't wget that URL (and I can when clustering is disabled on peers), so I'm guessing the master has just stopped trying. This is possibly just normal? It's the only operational cluster I have access to at the moment, and it's the simplest one imaginable, with a complete rebuild producing the same result.
