systemFlags in the Stats() collection is different between our UAT and PROD servers. Our UAT servers show 1 as the value and our PROD show 0.
Below is an example of what's returned in our UAT env't. But in our Prod env't the systemFlags is zero.

http://docs.mongodb.org/v2.6/reference/command/collStats/ states that it "Reports the flags on this collection that reflect internal server options. Typically this value is 1 and reflects the existence of an index on the _id field."
When querying UAT and PROD env'ts the getIndexes() show that an Index exists.
db.customer.getIndexes()
[
{
"v" : 1,
"key" : {
"_id" : 1
},
"name" : "_id_",
"ns" : "portfoliomanager.customer"
},......
Please advise what the Server uses this flag for, and why it may be reporting differently across env'ts.
