I have a problem with roundcubemail using postfix/Courier IMAP server.

I get a error imapd: Failed to create cache file: maildir_lock
imapd: Error: Disk quota exceeded

While i set the Disk quota exceeded to 5 gig and box has 3 gig.
I cant mail any more. I get error:

An error occurred while saving sent message.

How can i solve this ? Clear the cache ? I already restart imap service
and postfix. Problem not solved ???

Who know how to solve this ?
