Hi
Which partition is reported as being full?
As the system is a locked-down appliance it can be difficult to clear out files unless they are log files. I recall there were several bugs on CCM 5 which resulted in the system running low on disk space; it would probably be wise to open a TAC case.
TAC will be able to advise what to do to fix the system - they can get root access to the server and deleted problem files, and will be able to advise whether you need to upgrade to prevent the problem recurring.
Regards
Aaron
