Hi Nour - can you look into elasticsearch.log file during the time that this error occurs? There's likely more detail there...

Post the relevant section of that log here...

Communications between the elasticsearch JVM and the autodetect process (which ML runs) is done via named pipes, these pipes are created in /tmp. In the log there is a message that you posted, it mentions that a file in ES\_HOME/tmp cannot be read.

This /tmp directory must be readable, if it is mounted with no\_exec then autodetect cannot start.

/tmp is the default temporary directory the JVM uses but you can change this with the JVM option:

`-Djava.io.tmpdir=/var/data/elasticsearch/tmp`

You could try adding that setting to ES\_HOME/config/jvm.options without a suitable choice of tmpdir. This will required a restart of elasticsearch
