CPU values were around 40% > and disk was 50% full. > From what I understand, the coordinator asked for merkle trees from the other > two nodes. However one of the nodes fails to create his merkle tree. > Unfortunately we do not have a way to reproduce this problem. > The coordinator receives: > {noformat} > 2015-01-09T17:55:57.091+0100 INFO
