/var/log full but not showing full?

My /var/log is showing full (100%) on the dashboard but if I run 

du -sh /var/log/*

in the console I get this:

root@Tower:/var/log# du -sh /var/log/*
40K	/var/log/Xorg.0.log
0	/var/log/apcupsd.events
4.0K	/var/log/apcupsd.events.1

0	/var/log/spooler
0	/var/log/swtpm
308K	/var/log/syslog
8.0K	/var/log/wtmp

That's clearly less than either the default of 128M or the 384M that I have attempted to increase it in my go file using this line:

mount -o remount,size=384m /var/log

Can anyone shed any light on what might be using the extra space?

Diagnostic files attached.
