Dependency manager sync timeout after waiting 60s

Issue

• The following WARN can appear during the startup:

  WARN [http-nio-8080-exec-1][DependencyManagerSyncImpl:85] Dependency manager sync timeout after waiting 60s

Environment

• Liferay DXP 7.2, 7.3

Resolution

• DependencyManagerSyncImpl class was introduced on 7.2 (LPS-102056) to apply ComponentExecutorFactory for DM in order to enable concurrent activation.
  • The DependencyManagerSyncImpl waits, by default, 60 seconds for the initialization tasks to be completed.
  • If after that time they haven't finished the previous mentioned warning will appear.
• The following approaches can be followed (only if the message appears constantly and no other time consuming issues have been detected during the startup):
  
  • In order to increase the default time the following property can be configured in the portal-ext.properties file: module.framework.properties.dependency.manager.sync.timeout=60
  • The component activation thread pool can be directly disabled using, also in portal-ext.properties, the following property: module.framework.properties.dependency.manager.thread.pool.enabled=false This last option will prevent the WARN message from appearing but can lead to a not optimized startup since the activation will be done serially. It should be used only as a workaround until an appropriate value is found for the timeout.
