It's for second time this month that /var/log has two files kernlog and syslog each 12GB. It is caused by journald's over 100% CPU. I have deleted these files manually again, and set journalctl vaccum size to 200M, but I fear this problem may reoccur. Can anyone help please?

Another thing, is that suddenly /var/lib/snapd takes most of space on var. Is there a safe way to clean it up? I don't think I'm using snap at all.

Edit It happened again today (14.09).
