could it be just slow?
This is what I observed on block 6084: this apparently the separate point of new and old client. After this point, all the blocks generated by the old client will be rejected, there's apparently a chain of 200 blocks or so that have been rejected, so it will stuck at this point for a while, until it find the new chain, where the old chain will become orphans.
Once this is done, it will process normally for the new chain
