I am getting a Low Disk Space warning :
The volume ''log'' has only 0 bytes disk space remaining.
You can free up disk space by removing unused programs or files, or by moving
files
to another disk or partition.
When I click the examine button on the warning screen Disk Usage
Analyser is invoqued and gives the following correct report of /log (see
screen2.jpg)
So only 25.5 MB of the available 356.00 MB are actually used. I should
therefore not get this warning. A similar error gets reported from time
to time for partition /tmp
