+
+A process of unit @UNIT has been killed by the Linux kernel out-of-memory (OOM)
+killer logic. This usually indicates that the system is low on memory and that
+memory needed to be freed. A process associated with @UNIT@ has been determined
+as the best process to terminate and has been forcibly terminated by the
+kernel.
+
+Note that the memory pressure might or might not have been caused by @UNIT@.
