elasticsearchHow can I troubleshoot an issue with Elasticsearch unexpectedly exiting?
-
First, check the Elasticsearch log files for any errors. These can be found in the
logs
directory of the Elasticsearch installation. -
Check the system resources available to Elasticsearch. For example, you can run the following command to check the amount of memory being used by Elasticsearch:
$ ps -aux | grep elasticsearch
- Output of the above command should look like this:
elasticsearch 1234 0.0 0.2 1234 567 ? Ssl 10:34 0:00 /usr/bin/java -Xms1g -Xmx1g -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+AlwaysPreTouch -server -Xss1m -Djava.awt.headless=true -Dfile.encoding=UTF-8 -Djna.nosys=true -Djdk.io.permissionsUseCanonicalPath=true -Dio.netty.noUnsafe=true -Dio.netty.noKeySetOptimization=true -Dio.netty.recycler.maxCapacityPerThread=0 -Dlog4j.shutdownHookEnabled=false -Dlog4j2.disable.jmx=true -Dlog4j.skipJansi=true -XX:+HeapDumpOnOutOfMemoryError -Des.path.home=/usr/share/elasticsearch -cp /usr/share/elasticsearch/lib/* org.elasticsearch.bootstrap.Elasticsearch
-
If the amount of memory allocated to Elasticsearch is not sufficient, you can increase it by changing the
-Xms
and-Xmx
parameters in theelasticsearch.yml
configuration file. -
You can also check the system logs for any other errors that may be causing Elasticsearch to unexpectedly exit.
-
If the issue persists, you can try restarting Elasticsearch or even reinstalling it.
