51GB /var/dcc/log/

My /var/dcc/log/ directory has about 51GB of files that look like this:
8.0K -rw------- 1 root bin  6.6K May 26 05:10 msg.3wbrjV
 36K -rw------- 1 root bin   33K May 26 05:57 msg.3wbrJV
 12K -rw------- 1 root bin   11K May 27 10:03 msg.3wbRjv
 12K -rw------- 1 root bin  9.2K May 27 10:03 msg.3wbRjV

..All msg.[something]

Is it ok to get rid of these files?
