While running my test after some time i got below error like "java.lang.OutOfMemoryError: Java heap space"
Could some one please help me how to increase java heap space for jmeter.

For JMeter 4.0 default settings are:
-Xms1g -Xmx1g -X:MaxMetaspaceSize=256m
For Windows you can amend them in 2x times:
set HEAP="-Xms2g -Xmx2g -X:MaxMetaspaceSize=512m" && jmeter.bat
For Linux/Unix/Macosx:
export HEAP="-Xms2g -Xmx2g -X:MaxMetaspaceSize=512m" && ./jmeter.sh
Also make sure you're following JMeter Best Practices and recommendations from the 9 Easy Solutions for a JMeter Load Test “Out of Memory” Failure

I'm trying to upgrade our SonarQube from 6.7.4 to 7.9.3 but when execute:
SONARQUBE_HOME/bin/linux-x86-64/sonar.sh start
I got the following in the SONARQUBE_HOME/logs/sonar.log file:

If you need more info please let me know. Thanks a lot.
We found the issue.
The "wrapper.java.maxmemory" value in the "DO NOT EDIT THE FOLLOWING SECTIONS" part of the "SONARQUBE_HOME/conf/wrapper.conf" file was changed by mistake from "32" (The SonarQube starts pretty well) to "8" (OutOfMemoryError).
I'm using Sonarqube community version. I'm getting the following error,

I have Changed the size in sonar.properties, still I'm facing the same problem. How to solve this.
sonar.web.javaOpts=-Xmx4G -Xms2048m -XX:+HeapDumpOnOutOfMemoryError
sonar.ce.javaOpts =-Xmx4G -Xms2048m -XX:+HeapDumpOnOutOfMemoryError
sonar.search.javaOpts=-Xmx4G -Xms2048m -XX:+HeapDumpOnOutOfMemoryError
What you've changed are the settings that allocate memory to SonarQube itself.
What you need to change is the setting that allocates memory to the analysis process. You haven't said which analyzer you're using, so the details will vary a little, but
for SonarQube Scanner export SONAR_SCANNER_OPTS="-Xmx512m"
for SonarQube Scanner for Maven export MAVEN_OPTS="-Xmx512m"
Large files in Project cause this problem, for me a 50MB XML file gives this error and this file was not important to the analysis process. I excluded this file in the configuration file (SonarQube.Analysis.xml) and the problem was solved
I am running SonarQube 5.5 with the following wrapper config settings.
wrapper.java.initmemory=3
wrapper.java.maxmemory=4096
I am still getting the following stack trace, this project has run successfully with sonarqube 5.3.

Memory adjustments must be made in sonar.properties:
sonar.web.javaOpts (for Web Server JVM)
sonar.ce.javaOpts (for Compute Engine JVM)
sonar.search.javaOpts (for JVM running ElasticSearch).
In your case the memory exception occurs in a background task so it relates to Compute Engine (see SonarQube architecture for more insight).
Settings in wrapper.conf are not relevant here and should be left untouched (hence the # DO NOT EDIT THE FOLLOWING SECTIONS warning in the file).
I got this error when I run Jhipster project on Jrebel. I try to increase my java heap size until to 512m by insert this line to VM Argument on Arguments Tab, but can not solve the error. I want to ask what the cause of error and how to solve it?
${jrebel_args}
-Xms512m -Xmx1024m
[ERROR] org.springframework.boot.context.embedded.tomcat.ServletContextInitializerLifecycleListener - Error starting Tomcat context: org.springframework.beans.factory.BeanCreationException
Exception in thread "main"
Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "main"
Exception in thread "process reaper" Exception in thread "process reaper"
I solve this problem by add -XX:MaxPermSize=512m at VM Arguments (eclipse)
thanks to ZT (zeroturnaround) Support
Running JVM with JRebel will use up to 50% more memory, if it uses more then there is a problem. Just in case please try to double the max limit with -Xmx2048m . This must avoid the OutOfMemoryError . After that you can reduce it when observing the actual memory usage.
When I start to deploy my application, the build is successful but I get the following error while installing:
[exec] JVMDUMP039I Processing dump event "systhrow", detail "java/lang/OutOfMemoryError" at 2013/07/09 13:55:51 - please wait.

[exec] java.lang.OutOfMemoryError: java.lang.OutOfMemoryError: Java heap space
I tried increasing the heap size, but it didn't help. Can anybody help me out? I could not find a solution for deploying on WebSphere 8.0
Since I understand you are using wsadmin to do your deployment you might want to use something like:
wsadmin.bat -javaoption –Xms256m -javaoption –Xmx768m
when calling the wsadmin command.
More on this here and here.
