Memcached crashes caused all nodes on a windows ec2 cluster to remain in "pend" state

Cluster setup: c1:c2::5:5
biXDCR_bucket: c1 <---> c2
uniXDCR_src: c1 ---> c2 :uniXDCR_dest
Front end loads on c1 and c2 for biXDCR_bucket, and on c1 for uniXDCR_src.
c1: http://ec2-54-234-1-196.compute-1.amazonaws.com:8091/
c2: http://ec2-50-19-189-64.compute-1.amazonaws.com:8091/

• All nodes on c1 in pend state.
• cbstats says that warm_thread on all these nodes is complete.
• cbstats states that all vbuckets are dead.
