How to disable EDAC mod

hi everyone,my / used 100%:
root@kinsuncloud:~# df -h
Filesystem Size Used Avail Use% Mounted on
udev 10M 0 10M 0% /dev
tmpfs 3.2G 476K 3.2G 1% /run
/dev/mapper/pve-root 95G 0G 95G 100% /


so,i restart the server,than,i see a lots of errors:
EDAC sbridge:Lost memory errors

i think maybe many logs in /var/log/,so i used
rm -fr /var/log/*
lsof |grep delete
kill -9 3318
and then,the / now ok,
root@kinsuncloud:~# df -h
Filesystem Size Used Avail Use% Mounted on
udev 10M 0 10M 0% /dev
tmpfs 3.2G 476K 3.2G 1% /run
/dev/mapper/pve-root 95G 1.5G 89G 2% /
