      Summary

      Windows Elastic Agents are OOMing under default configurations when deploying third-party plugins and slows down agent start-up performance.

      Environment

      • Windows Elastic Agents

      Steps to Reproduce

      1. Install a third-party plugin, such as Artifactory
      2. Start a Windows Elastic Agent

      Expected Results

      Agent can successfully deploy the plugin on start-up

      Actual Results

      The below exception is thrown in the bamboo-elastic-agent.out file:

      Workaround

      Set the following into the Instance startup script for the image at Bamboo Administration >> Image Configurations >> Edit

      Option 1

      Requires sed to be installed in the image which is included in our stock images but may not existing in a custom AMI.

      sed -i "s/-Dimagefiles/-Dbamboo.agent.syncOnly -Dimagefiles/" C:\opt\bamboo-elastic-agent\bin\bamboo-elastic-agent.bat
sed -i 's@cd %%OLD_PWD%%@sed -i \'s/-Xmx256m/-Xmx512m/\' \%%TEMP\%%\\\\bamboo-agent-bootstrap-1.bat\n\%%TEMP\%%\\\\bamboo-agent-bootstrap-1.bat ^>^>bamboo-elastic-agent.out 2^>\^&1\ncd %%OLD_PWD%%@' C:\opt\bamboo-elastic-agent\bin\bamboo-elastic-agent.bat
      Option 2:
      setx -m _JAVA_OPTIONS "-Xms256m -Xmx512m"

      This is a global Java variable, so any java processes that run during your builds (e.g. Gradle and Maven) will also inherit this config for their respective JVMs.
