[SOLVED] Job for puppetserver.service failed because the control process exited with error code

Job for puppetserver.service failed because the control process exited with error code

Puppet: 5.3.3
OS: Ubuntu Xenial (virtual box) Inbuilt RAM: 4GB

I am new to Puppet. After installing Puppet v5.3.3, I wanted to start the server:

systemctl start puppetserver (or service puppetserver start)

This gave me following error:
Job for puppetserver.service failed because the control process exited with error code. See "systemctl status puppetserver.service" and "journalctl -xe" for details.

systemctl status puppetserver.service

    Jan 24 13:08:28 master systemd[1]: Starting puppetserver Service...

I followed a few blogs (blog1, blog2)that explained
- first identify the free memory: free -m (look mem row, free tab)
- change memory allocation of file puppetserver

vi /etc/default/puppetserver

    ###########################################  
    # Init settings for puppetserver  
    ###########################################  

    # Location of your Java binary (version 7 or higher)
    JAVA_BIN="/usr/bin/java"

    # Modify this if you'd like to change the memory allocation, enable JMX, etc
    JAVA_ARGS="-Xms400m -Xmx400m -        Djruby.logger.class=com.puppetlabs.jruby_utils.jruby.Slf4jLogger"

    # These normally shouldn't need to be edited if using OS packages
    USER="puppet"
    GROUP="puppet"
    INSTALL_DIR="/opt/puppetlabs/server/apps/puppetserver"
    CONFIG="/etc/puppetlabs/puppetserver/conf.d"

    # Bootstrap path
        BOOTSTRAP_CONFIG="/etc/puppetlabs/puppetserver/services.d/,/opt/puppetlabs/server/apps/puppetserver/config/services.d/"

Even after reducing memory, I was not able to start puppetserver. Please help, where i am going wrong.

Solution

Changed memory to 250m (JAVA_ARGS="-Xms250m -Xmx250m). It worked.
May be its 50% of free memory (free -m)

free memory was 440 initially. i kept 400 in JAVA_ARGS initially.
