Customer noticed several errors in error.log on both Author and Publish Instances:
- Author error.log:
*ERROR* aem-api-metrics FrameworkEvent ERROR (org.apache.felix.log.LogException: org.osgi.framework.ServiceException: ServiceFactory.getService() resulted in a cycle.)
org.apache.felix.log.LogException: org.osgi.framework.ServiceException: ServiceFactory.getService() resulted in a cycle.
*ERROR* org.apache.sling.engine.impl.SlingHttpContext handleSecurity: AuthenticationSupport service missing. Cannot authenticate request.
*ERROR* org.apache.sling.engine.impl.SlingHttpContext handleSecurity: Possible reason is missing Repository service. Check AuthenticationSupport dependencies.
- Publisher error.log
*ERROR* ROOT bundle org.apache.felix.scr:2.1.30 (32) Circular reference detected trying to get service com.adobe.cq.wcm.translation.impl.sync.LanguageCopySynchronizer
Analyzing the error logs provided by the customer, it was noticed that at the time the errors appeared, the instances were still in “Startup” mode, not all bundles being started - e.g. “StartupListenerTracker Startup progress: 83% (bundles 489/587)” . Therefore, the errors occurred as not all bundles were started.
During a restart, or anything that causes a restart such as installing or reinstalling bundles or packages that trigger a re-register of OSGi bundles, this kind of exceptions can be common.
If the errors are noticed after an instance is fully started, all bundles being active, please open a ticket with Adobe Support for further investigations.
