I am getting an error Logstash - java.lang.OutOfMemoryError: Java heap space. However, I have changed the heap memory in the jvm.options file from 1g to 2g to 8g to 10g. I am still getting the same errors though. How can I find out how much heap space I need to use or am I supposed to make a different change in this or another file elsewhere. ---

how much memory your system has? are you getting this error when you start or after a while any other error messages on log files /var/log/messages or dmesg? you can download free java debugger and find try. it will be long hard process if you do not know java (was for me) ---

For the error in the /var/log/elasticsearch I am getting a org.elasticsearch.action.search.SearchPhaseExecutionException: all shards failed The error also comes about after a while when the logstash has already been run successfully. ---

Hi @edster, it looks like the OutOfMemoryError happens in logstash. You probably want to take your discussion to the logstash forum: [https://discuss.elastic.co/c/logstash](https://discuss.elastic.co/c/logstash) ---
