Also, we can have up to 1 GB of metaspace (1048576 K).

The current capacity of the metaspace is around 13.5 MB (13724 K).G1 regions are 1 MB, there are 43 regions marked as young, and 3 as survivors space.The first line reports the current heap size as 202 MB (206848 K) – also, 42 MB (43061 K) is being used.I found the following site useful for understanding Java maximum and permanent generation heap sizes. JAVA_ARGS='-Xmx1048m -XX:MaxPermSize=512m'Īfter making a change, restart Jenkins gracefully from the Jenkins web interface, or force an immediate restart from the command-line with sudo /etc/init.d/jenkins restart. If you also set MaxPermSpace, you need to add a space between the parameters): # arguments to pass to java This is how it would look if you set the heap space to be 1 GB: # arguments to pass to javaīe careful not to set the heap size too large, as whatever you allocate reduces the amount of memory available to the operating system and other programs, which could cause excessive paging (memory swapped back and forth between RAM and the swap disc, which will slow your system down). The permanent generation heap holds meta information about user classes.įor example, this extract is from the default /etc/default/jenkins after a fresh install of Jenkins: # arguments to pass to java To add more PermGen space, add the parameter XX:MaxPermSize=512m (replace 512 with something else if you want more.That sets the maximum size of the memory allocation pool (the garbage collected heap). To add more Java heap space, increase the value of the -Xmx Java parameter.On Ubuntu 12.04 LTS, uncomment the JAVA_ARGS setting on line ten of /etc/default/jenkins: The value of the -Xmx parameter will have no affect on this error. : PermGen space – this means you need to increase theĪmount of generation space allocated to store Java object metadata.Need to increase the amount of heap space allocated to Jenkins when There are two types of OutOfMemoryError messages that you might encounter while a Jenkins job runs: But I used the Ubuntu Package Manager, aptitude, or apt-get to install Jenkins, and I don't know where to look to change the amount of heap space allocated to Jenkins.

My Jenkins jobs are running out of memory, giving messages in the build log.
