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).

I am running an grails application for my project in IntelliJ and I have set the vm options to :
-Dserver.port=8080 -Xms3g -Xmx3g -XX:-UseGCOverheadLimit -Xverify:none
The logs are :
Running Grails application
Invalid maximum heap size: -Xmx4096M
The specified size exceeds the maximum representable size.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Error | Forked Grails VM exited with error
Please help me with that ?
I have no chance to write comment, that's why I am writing answer directly.
If your JVM is 32bit, then heap size should lower than 4gb. Either you can install 64bit JVM, or set the maximum heapspace to 2GB with -Xmx2048M. I had similar problem and this worked for me, hope this helps you as well
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.
I'm running Jenkins on Windows 2016 server with the following defenitions in jenkins.xml:
-Xrs -Xmx2G -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "%BASE%\jenkins.war" --httpPort=8080 --webroot="%BASE%\war"
But the problem that we get an error:
exception while collecting data: java.lang.OutOfMemoryError: Java heap space java.lang.OutOfMemoryError: Java heap space
and the server stuck.
After monitorung the master, we have seen that java heap is 512 and not 2G. How can it be?
From the Master monitor screen:

Beside verifying what's in jenkins.xml file, have a look at environment variable(s) like:
JAVA_OPTS, MAVEN_OPTS or ANT_OPTS.
I am running java developer IDE and in a process of trouble shooting a module . For this i have increased the logging memory of the tool, Now when logging it error is coming on console as
Uncaught exception
java.lang.OutOfMemoryError: Java heap space
i am using below command for increasing memory
"-XX:CompileThreshold=8000 -XX:PermSize=192m -XX:MaxPermSize=2g -Xms2g -Xmx2g"
earlier it is
"-XX:CompileThreshold=8000 -XX:PermSize=192m -XX:MaxPermSize=1024m -Xms1024m -Xmx1024m"
my system memory is 16 GB through the command cat /proc/meminfo
but the system free memory is less than 1 GB when exception
Uncaught exception
java.lang.OutOfMemoryError: Java heap space
is coming , I have allocated maximum memory to be utilized as 2gb
-XX:MaxPermSize=2g
but it is occupying approximately all available memory.
Do not know whether this command is help full or not whether could i assign more memory like below command
"-XX:CompileThreshold=8000 -XX:PermSize=192m -XX:MaxPermSize=10g -Xms10g -Xmx10g"
increasing it to 10g will be good or not , or is there any problem with my command.
Use -Xms1024m -Xmx1024m to control your heap size (1024m is only for demonstration, the exact number depends your system memory). Setting minimum and maximum heap size to the same is usually a best practice since JVM doesn't have to increase heap size at runtime
I recently upgraded my grails application from grails 1.3.6 to grails 2.3. Up-gradation process completed successfully with required changes.
Now i'm facing a problem please see stack-trace:
| Running Grails application
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Invalid maximum heap size: -Xmx4096m
The specified size exceeds the maximum representable size.
| Error Forked Grails VM exited with error`
Any help??
Thanks
It looks like you're running a 32bit version of the JVM, which will only support a max heap size of 2 gigabytes, not 4 gigabytes.
Find out what version of the JDK / JRE Grails is using. Then see whether you can change it to a 64 bit VM if you need 4 gigs of heap space. Otherwise, amend your startup parameters so that the JVM only requests a 2 gig heap size when Grails spawns it.
