I solved this on my 6.1 station by removing scemd.log and link it to /dev/null, which is kind of logging to nowhere. Of course, you won't be able to see the log contents this way.
This can be done by enabling ssh, log in and execute the following commands.
sudo -i
rm /var/log/scemd.log; ln -s /dev/null /var/log/scemd.log
I don't remember if a restart was needed but I think it does.
I always wanted to test if I can redirect the logs to an UBS stick but I didn't have the time for this.
