Resolved Domains view show wrong disk usage

[OverWolf]

Hi,
I'm on 17.5.3u24 and when I look disk usage from domains view, it show me a costumer that has used more space from that I can see in the hosting space.
This costumer have a big file (about 645MB) and last week disk usage was correct. But since two days ago disk usage it's exactly double (about 1290MB).

Why ?

Possibly your client is uploading content with great weight or has some type of error and the log files are growing too
