Exchange Catalog Job Failure - 0xe00002f7 Cannot Extract Mailbox - VFF Open Failure

Using BE 2014 and its driving me nuts. 

One of the Exchange Incremental Backup keeps failing! It has been fine for a while. Other databases on the same server dont seem to return this error. 

Completed status: Failed
Final error: 0xe00002f7 - Cannot extract mailbox messages from the Exchange backup. Review the job log for more information.
Final error category: Resource Errors

Catalog- \\MAIL01.X.ORG\Microsoft Information Store\X Mailstore
V-79-57344-759 - Unable to complete the operation for the following reason: VFF Open Failure. This can be caused by low memory or disk resources. 

I tried these and it did not help. Also restarted all BE Services.
