Description

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

Install a third-party plugin, such as Artifactory
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:

2018-11-14 08:02:14,797 ERROR [AgentRunnerThread] [ScanningPluginLoader] Unable to deploy plugin 'org.jfrog.bamboo.bamboo-artifactory-plugin' from 'Unit: C:\Users\Bamboo\bamboo-agent-home\plugins\user-installed\bamboo-artifactory-plugin-2.5.1.jar (1542182479271)'.

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.
