Attachment limit reached - user set to unlimited

[PeterWhitlam]

Hosted site running 4.6.11

We have had a number of users contact us saying they cannot add any more attachments as they have reached their limit. Site is running as unlimited attachments  as seen in screenshot.

Is there a physical number of files (this user has 997) or is this a bug..?

Could you please provide me with an example user, so I can take a look?
