Will mongodump throw an error if there is a roll over in between the dump?

Hi,

I have continuous input/output operations happening on my MongoDB single node replica set server. I take full backup using snapshot, followed by backup of oplog collection at regular intervals .
My query is, while mongodump is running, if there is oplog roll over will mongodump throw an error? Will roll over be identified during mongodump of oplog collection?

Thanks,
