## issue
my issue seems strange, i created a cluster with es , when the first time I started it after config , everything seems good , no error. but after a day time (more than 24h but no more thann 48h) , i resatart it , i met the error below .
then i download a new es and try to start , it works well , so i try to compare the diff between the old es and the new-download one .
finaly i find some differ in the dictory ` elasticsearch-7.0.0/modules/x-pack-ml/platform/linux-x86_64/lib/`
the obvious differ is the `liblog4cxx.so.10` change to `liblog4cxx.so.10.gz`
i have done nothing after started
if i replace the old es`s dir ```elasticsearch-7.0.0/modules/x-pack-ml/platform/linux-x86_64/lib/``` with the new es`s ๏ผ it seems every thing ok .
what may be the problem?

Hi, friend, i am have same error, but i am installing packaged version 7.1.0. (CentOS 7.6 x86\_64) from repository. I read here on the forum that this is because the ML plugin is trying to start its own process, you probably saw this topic. I added the "xpack.ml.enabled: false" parameter to the elasticsearch.yaml file and the error was gone. However, the learning machine doesn't work either. And there was an error caused /usr/share/elasticsearch/modules/x-pack-ml/platform/linux-x86\_64/bin/controller.
Come on, maybe together we will try to figure it out?
My timezone +3, write, me, please, when you know news?

I am getting below exception: org.elasticsearch.bootstrap.StartupException: ElasticsearchException[Failed to create native process factories for Machine Learning]; nested: FileNotFoundException[\.\pipe\controller\_log\_13044 (The system cannot find the file specified)]; Can anyone suggest me what can i do to resolve the same? Thanks & Regards, Priyanka Y.
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? ๐คช
I am trying other temp-directory with owner "elasticsearch", changing version of Java, but don`t understand, why this "very bad" process cannot running. ๐ก
I will patiently study the documentation. ๐
If I can understand, I will write here.

One guess is that some overzealous log compressor on your system has compressed one of our shared libraries, `liblog4cxx.so.10` (presumably because it contains `log` as part of its name).
This file should NOT be compressed to a .gz file.
