Rebalance fails when creating/querying views during rebalance

Rebalance fails when creating/querying views during rebalance

Steps to reproduce:

-Install CB build#1453 with 1024 vbuckets
-Load 1000 json docs
-Add 3 nodes
-Start Rebalance
-During rebalance create multiple ddocs/views and query each view after creating

View query is successful for 1 ddoc, 3 views. Create one more ddoc, view. Query the view. Below error is shown:

{
"from": "local",
"reason": "{db_open_error,<<\"default/86\">>,\n

{not_found,no_db_file},\n <<\"Couldn't open database `default/86`, reason: {not_found,no_db_file}

\">>}"
}
and rebalance fails.

Below error and crash report can be seen in the diagnostics:
