Nothing of interesting..
File liblog4cxx.so.10 exists on my system without changes. I think he is not guilty of anything. I think the system is trying to create something in the /tmp directory for the running Learning Machine, but cannot do it, so the process crashes.
The problem is that I don't know if I need a learning machine or not? 
I am trying other temp-directory with owner "elasticsearch", changing version of Java, but don`t understand, why this "very bad" process cannot running. 
I will patiently study the documentation. 
If I can understand, I will write here.
