ElasticSearch 2.4.6 does not start at all without any error message Ubuntu 16.04

Trying to start elasticsearch 2.4.6 with ./elasticsearch in the bin direcytory. It just closes and nothing happens. See the below screenshot

ElasticSearch 2.4.6

Stepping through the starter scripts, I can see that it comes until exec "$JAVA" $JAVA_OPTS $ES_JAVA_OPTS -Des.path.home="$ES_HOME" -cp "$ES_CLASSPATH" org.elasticsearch.bootstrap.Elasticsearch start "$@" line and then closes.

However, please note that elasticsearch 5.* does not have this problem and starts normally without errorElasticSearch 5.*

Can anyone tell me what could possibly be causing this? Or at least where can I find any error log. No error is logged in logs file of elasticsearch.

Solution

  • The problem was due to a kernel bug due to a fix for meltdown vulnerability. It is fixed by downgrading the kernel. (Or upgrading elasticsearch or the kernel as for now.)
