Hello,

The best method to try further debug the issue would be to increase the error level on the server with the error in the web.config and check if there is any information as to when the disk space does fail.

We can take a look at this via paid support if you prefer using the contact form at the top of the site.

In which section of  web.config, we can increase the error level on the server with the error?

By default,we should see the errors in local server!

Besides,we dont have any problem in calculating Disk Space, The Issue is just for Bandwidth Calculation. the solidCP  is not showing any error.
