I suspect (but don't know for sure) that the problem here is that ZK is limited to 1M at the moment, although this is configurable (sorry, don't have the reference handy).
But at 3,000 cores you're certainly going into relatively uncharted territory so I'm unsurprised that you're running into edge cases. You can try to change the size that is allowed for ZK. Or consider using fewer cores and limiting the contents returned with the appropriate fq clause. Note that the whole transient core stuff is _not_ supported in SolrCloud (yet, although there is some interest).
