Hi Matt,

I'm not sure what munge is, it's not something provided with Galaxy.  Googling 
suggests it might be an authentication tool used in some HPC environments.  
Without having any familiarity with it, I can't say what process in Galaxy 
would be interacting with it, especially since that interaction must occur 
implicitly somewhere down the chain of normal Galaxy operations.
