I started getting a few of these this morning:

ProcessBlock: ORPHAN BLOCK, prev=00000000000049aaab5e
ProcessBlock: ORPHAN BLOCK, prev=0000000001b0b1aa5309
ProcessBlock: ORPHAN BLOCK, prev=00000000016e2617943a
ProcessBlock: ORPHAN BLOCK, prev=0000000001aa515daf6a
ProcessBlock: ORPHAN BLOCK, prev=0000000001acdbf89780
ProcessBlock: ORPHAN BLOCK, prev=0000000001c23469de6c

I have the log piped to a text file if you want it.
