massive QMMM output file and system setup

[tuf6... at temple.edu]

Hello CP2K users,
I am running QMMM simulation of 1 di alanine in 5000 methanol molecules. My 
system deals with alanine and 25 methanol molecule in QM region and rest in 
MM region using the attached input file. 
I want to know why my alanine.out file is huge as for only 1000 steps it is 
~3 GB.
My main question is that is this input file is good enough to start qmmm or 
i need some additional parameters....
I hv doubt about some key point mentioned in input file in

* bold redThank you *
