I've noticed tha the Virtualhost quota is doubled after a quotacheck via Virtualmin tool. In this way a lot of Virtualhosts are overquota but the effective homedir size is half the quota indicated by Virtualmin!
In these Virtualhosts i have enabled the chroot jail.
In Virtualhosts where chroot jail is not enabled, the quota count match the homedir size.
What i am doing wrong?
Thank you for you help/suggestions.
