Mavericks Server preventing Mac Mini to sleep

Question

Hi everyone,
I am using my Mac Mini Server without webhosting (just for file sharing) and I would like it to go to sleep when I am not using it. The idea is to be able to turn it on with WOL when I need it and let it sleep otherwise.
The problem is: it wont go to sleep! I can only put it to sleep manually and even than it wakes up after a while. This is the report I get when I use pmset -g assertions command in the Terminal:

Is there anything I can change or do to make my Mac go to sleep normally?
P.S. I am aware that several people asked this question for previous Mac Os X versions but I didnt find any topic for Maverics (at least none which had the solution in it).

Hello eklisiarh,
I am having this problem too. My osx server won´t go to sleep as well.
I have gotten down to eliminate alle daemons except the com.apple.collabd. This is very annoying. I need the server to go to sleep.
I have switched everything off. I even killed the process shown below. But it did a respawn (just as I had expected).
Are we the only ones who are thinking about that?
I do not want to go into the config files of that deamon without guidance.
