Hi Team, We are using JDBC input for oracle connectivity and executing multiple queries. Now I am getting JVM error in logs. Can you suggest RAM for JDBC input, to avoid this error. Current RAM size in 15GB and logstash version is logstash-7.3.2-1.noarch Error:- jvm\_args: -Xms4g -Xmx4g -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -Djava.awt.headless=true -Dfile.encoding=UTF-8 -Djruby.compile.invokedynamic=true -Djruby.jit.threshold=0 -Djruby.regexp.interruptible=true -XX:+HeapDumpOnOutOfMemoryError -Djava.security.egd=file:/dev/urandom java\_command: org.logstash.Logstash -f raghav.conf java\_class\_path (initial): /usr/share/logstash/logstash-core/lib/jars/animal-sniffer-annotations-1.14.jar:/usr/share/logstash/logstash-core/lib/jars/commons-codec-1.11.jar:/usr/share/logstash/logstash-core/lib/jars/commons-compiler-3.0.11.jar:/usr/share/logstash/logstash-core/lib/jars/error\_prone\_annotations-2.0.18.jar:/usr/share/logstash/logstash-core/lib/jars/google-java-format-1.1.jar:/usr/share/logstash/logstash-core/lib/jars/gradle-license-report-0.7.1.jar:/usr/share/logstash/logstash-core/lib/jars/guava-22.0.jar:/usr/share/logstash/logstash-core/lib/jars/j2objc-annotations-1.1.jar:/usr/share/logstash/logstash-core/lib/jars/jackson-annotations-2.9.9.jar:/usr/share/logstash/logstash-core/lib/jars/jackson-core-2.9.9.jar:/usr/share/logstash/logstash-core/lib/jars/jackson-databind-2.9.9.3.jar:/usr/share/logstash/logstash-core/lib/jars/jackson-dataformat-cbor-2.9.9.jar:/usr/share/logstash/logstash-core/lib/jars/janino-3.0.11.jar:/usr/share/logstash/logstash-core/lib/jars/javassist-3.24.0-GA.jar:/usr/share/logstash/logstash-core/lib/jars/jruby-complete-9.2.7.0.jar:/usr/share/logstash/logstash-core/lib/jars/jsr305-1.3.9.jar:/usr/share/logstash/logstash-core/lib/jars/log4j-api-2.11.1.jar:/usr/share/logstash/logstash-core/lib/jars/log4j-core-2.11.1.jar:/usr/share/logstash/logstash-core/lib/jars/log4j-slf4j-impl-2.11.1.jar:/usr/share/logstash/logstash-core/lib/jars/logstash-core.jar:/usr/share/logstash/logstash-core/lib/jars/org.eclipse.core.commands-3.6.0.jar:/usr/share/logstash/logstash-core/lib/jars/org.eclipse.core.contenttype-3.4.100.jar:/usr/share/logstash/logstash-core/lib/jars/org.eclipse.core.expressions-3.4.300.jar:/usr/share/logstash/logstash-core/lib/jars/org.eclipse.core.filesystem-1.3.100.jar:/usr/share/logstash/logstash-core/lib/jars/org.eclipse.core.jobs-3.5.100.jar:/usr/share/logstash/logstash-core/lib/jars/org.eclipse.core.resources-3.7.100.jar:/usr/share/logstash/logstash-core/lib/jars/org.eclipse.core.runtime-3.7.0.jar:/usr/share/logstash/logstash-c Launcher Type: SUN\_STANDARD ---
