This is a large loaf of rye bread -9 lbs. made today. Today and the last time it has developed the large splits that appear in the photo. Prior to these last 2 cases it has not split.  I realize that it is advised to score a loaf such as this prior to baking but we have not done so in the past and have had no issues.  Any thoughts on why we are suddenly getting these splits/cracks would be appreciated.

Thanks.
