Users unable to change greeting - "System is Full Message"

[miteltravis]

This 3300 is fairly clean.  There are almost no voicemails on it - and voicemail works without issue.  Users (there are only 9) can set the directory names ok, but if they try to set or change a greeting, they get a "System is Full" message and cannot proceed.  There are no errors or alarms that stick out or lead me to believe the system is having issues.  Diskspace looks great - hardly anything used.  There is a total of 4 voicemails on the server in all.

I saw somewhere that log files could fill things up, but that just doesn't seem to be the case.  Any ideas?

How long has the system been up for

I rebooted it last night to see if that would fix the issue, sadly it did not.  Prior to that maybe a few months or so.
