Can't see any problems there - do have an blockheight for me to check?
Might be a probelm on coinex - but couldn't tell.
http://www.coin-base.org/dem/ runs fine atm.
This is what happens when pool is submitting a block:
ThreadRPCServer method=submitblock
******* exception encountered *******

Any help appreciated. This also happened few weeks ago, and then solved itself after a few hours. Just wondering if we could get some more debug info to figure out what is happening there.
