Redshift Cluster Resizing stuck at 97%

Hi, this is the second time when I have tried to resize the redshift cluster using "classic" resize from node type ra3.xlplus(12nodes) to ra3.4xlarge(2nodes) and the process get stuck after transferring 97% of data. It is stuck for the last 22hrs (by the time I am writing this question). The targeted resize cluster is getting restarted every 2mins. Did anyone face such a problem before?
