Possible Cause:  When the volume is out of disk space, this message will be broadcast to all users on the system. All attempts to write to files will fail because of insufficient disk space. The second line of the message indicates that deleted files have not yet been purged. The third line indicates that all the deleted files cannot be purged yet because the preset purge time has not elapsed. Users might not be able to save files they are using and might lose data.

Action:  See "Resolving Server Disk Space Problems in the Server Operating System Administration Guide.
