You are referring to comm ^^ ?

http://lxr.linux.no/linux/include/linux/sched.h#L201

The define is 16 characters long. This is to give you a hint about what it is 
that the interpreter might be executing. When its full path, you only get the 
first 16 chars, when someone just uses the command name and lets the shell 
find it, its more likely what you wanted.

comm is not 100% trustworthy but it helps you figure out what was being 
interpreted. My guess would be audit-viewer in this case.
