I am have been using neo4j-community-2.0.0-M04 and all of a sudden the neo4j database has started giving
Caused by: java.lang.OutOfMemoryError: Java heap space
Here is the log extract from neo4j server logs: http://pastebin.com/Lr0guH1F
Neo4j system startup command is shown below:
Using additional JVM arguments: -server -XX:+DisableExplicitGC
-Dorg.neo4j.server.properties=conf/neo4j-server.properties -Djava.util.logging.config.file=conf/logging.properties -Dlog4j.configuration=file:conf/log4j.properties -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -Xms1200m -Xmx1512m
The Server has 1.7GB memory. I have tried reducing the memory from 1200MB to 512MB but that doesn't work either.
Not sure what can be done.

I am constantly getting OutofMemory Error. Any idea how to resolve this? Jenkins current version 2.361. Jenkins server have 4 CPU # 2.40GHZ. RAM 16 GB
Entry in jenkins.xml for heap size is as below.
<arguments>-Dpermissive-script-security.enabled=no_security -Xss16m -Xms1024m -Xmx6144m
Jenkins is configured for JDK 11 from IBM Semeru (see below).

Server Environment: SonarQube – 6.7.7 and Openjdk version - "1.8.0_222"
Problem: Suddenly our sonarqube web application started hanging. From sonar.log found the below errors.
java.lang.OutOfMemoryError: GC overhead limit exceeded
Dumping heap to java_pid21155.hprof ...
Heap dump file created [10548624193 bytes in 50.277 secs]
TERM trapped. Shutting down.
To fix the same. Increased values for Web Server, Compute Engine and Elastic Search values in $SONAR_HOME/conf/sonar.properties file.
Web Server:
sonar.web.javaOpts=-Xmx8G -Xms512m -XX:+HeapDumpOnOutOfMemoryError
Compute Engine:
sonar.ce.javaOpts=-Xmx8G -Xms512m -XX:+HeapDumpOnOutOfMemoryError
Elastic Search:
sonar.search.javaOpts=-Xms6G -Xmx6G -XX:+HeapDumpOnOutOfMemoryError
But didn’t work. Then found service was running with jre path - /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.222.b10-0.el7_6.x86_64/jre/bin/java. So updated below in $SONAR_HOME/conf/wrapper.conf file
wrapper.java.command=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.222.b10-0.el7_6.x86_64/bin/java
But after service restart still it runs jre/bin/java only. Then i have configured JAVA_HOME pointing to my JDK but still it is running through jre, Any inputs would help to address the problem.
Problem solved by increasing the -Xms512m value to -Xms4G parameters of Web server, Compute Engine and Elastic search.
Our web application keep on crashing with error message as "GC overhead limit exceeded" after 30 minutes from start time.
I generated heap dump at that moment and loaded into eclipse MAT. It mentioned that TDSPacket as the problem suspect. As this is the library we are using to connect to SQL server, I am unable to trouble shoot from here.
Any suggestion please. Here are the JAVA_OPTIONS used.
-XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=D:\Apps\Logs\tomcat\memory -Xms2g -Xmx2g -XX:+UseG1GC -XX:+DisableExplicitGC -Xloggc:gc.log -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps -XX:+PrintGC -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=50 -XX:GCLogFileSize=2M exit -Xms2048m -Xmx2048m

I have the same problem which triggered after i changed vmoptions file.This worked for me
Go to C:\Users\ username \.androidStudio\
2.Find the studio.exe.vmoptions (or studio64.exe.vmoptions) and simply type
-Xmx4g (or -Xmx2g if you want to allocate 2GB RAM)
Here 4g is for allocating 4GB RAM to android studio.
Open file located at
/Applications/Android\ Studio.app/Contents/bin/studio.vmoptions
Change the content to
-Xms128m
-Xmx4096m
-XX:MaxPermSize=1024m
-XX:ReservedCodeCacheSize=200m
-XX:+UseCompressedOops
Xmx specifies the maximum memory allocation pool for a Java Virtual Machine (JVM), while Xms specifies the initial memory allocation pool. Your JVM will be started with Xms amount of memory and will be able to use a maximum of Xmx amount of memory.
Save the studio.vmoptions file and restart Android Studio.
I'm running Tomcat 7 as a windows service in a Windows Server 2008 Machine. I've got a Java.lang.OutOfMemoryError: PermGen space so I'm trying to increase its PermGen memory heap. So I specify this line at the end of JVM options:
-XX:PermSize=512m -XX:MaxPermSize=512m -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled -XX:+HeapDumpOnOutOfMemoryError
As specified in the picture below:
The server is properly launched, however I cannot get the permgen size increased. When I enter Tomcat's management GUI, I can see the memory near the limit (the line at the end, PS Perm Gen):
So the application gets stuck after a while. Why is not Tomcat changing this value?
As of my experience you are allowed to put only one option per line.
