Summary
New users or groups added to the external user directory are not available in Bamboo after executing synchronisation. The last synchronisation status and Cog icon>Overview>User Directories page mentions: "Synchronisation failed. See server logs for details."
Environment
Bamboo 6.6+ instance connected to any external user directory (LDAP, Active Directory, Jira, Crowd...)
Diagnosis
java.lang.OutOfMemoryError errors can be found at the atlassian-bamboo.log file:
ERROR [JobLauncher] Scheduled job with ID 'com.atlassian.crowd.manager.directory.monitor.poller.DirectoryPollerManager' failed
com.atlassian.util.concurrent.LazyReference$InitializationException: java.lang.OutOfMemoryError: GC overhead limit exceeded
Cause
The user synchronisation uses heap memory to process the data coming from the external user directory, if Bamboo does not have enough heap space to accommodate this data, the synchronisation will fail and new users will not be available.
Solution
- Stop Bamboo
- Increase the heap memory in Bamboo instance by changing the configurations below:
- Linux: JVM_MINIMUM_MEMORY and JVM_MAXIMUM_MEMORY parameters
- Windows: Initial memory pool and Maximum memory pool options
- Start Bamboo back
For more information on how to change these configurations, please see this article: Configuring your system properties.
