Hello.. I get the following logstash error Specify -J-Xmx####m to increase it (#### = cap size in MB). Specify -w for full OutOfMemoryError stack trace" I am not sure which configuration file I should change. Currently, I run logstash using systemctl start logstash I am running on Centos and I can't locate logstash.yml or jvm.options. thanks in advance for your help best Rajesh ---

Looks like the config was in /etc/sysconfig/logstash. # Arguments to pass to java LS\_HEAP\_SIZE="2g" #LS\_JAVA\_OPTS="-Djava.io.tmpdir=$HOME" ---
