can-i-remove-files-in-var-log-journal-and-var-cache-abrt-di-usr

Yes, the files from /var/log/journal directory can be removed.

The nicest method I've found is:

sudo journalctl --vacuum-size=500M

which deletes old log-files from /var/log/journal until total size of the directory becomes under specified threshold (500 megabytes in this example).

You can also clean based on time: journalctl --vacuum-time=10d
