memcached exited with status 139 after restart couchbase server in failover add back test.

Create a cluster of 3 nodes couchbase server 2.0.0r-266 on ec2.
Use mcsoda to load 200000 items to cluster.
Do some failover and add back test
Shutdown couchbase server in all nodes and restart again
See lost item at master node
Check log, see memcached exit with status 139
