I am facing the classic HTTP error 503 while restarting my AEM instance.

Error logs state the following

Possible reason is missing repository service. Check AuthenticationSupport dependencies

I have checked that my bundle "Apache Sling Authentication Service (org.apache.sling.auth.core)" is active

I have followed the steps mentioned in this post

I have given the instance a good one hour to start completely

None of the above steps helped fix my issue.

Please suggest any methods you're aware of to troubleshoot this issue. I'm so stuck.

I had the same issue it was caused by a custom repoinit script that was deployed under crx-quickstart/launchpad/config/org/apache/sling/jcr/repoinit that was causing the repository service to fail on start. Most likely the activate function is runnig the repoinit scripts and silently dying.

Best thing to do is remove any custom repoinit scripts and restart the instance. If you have multiple of them the just delete them one at a time, but leave the OOTB ones there.

Hi @apoorva_arza ,

Try to delete below 2 files and restart the instance:

/author/crx-quickstart/repository/segmentstore/repo.lock

/author/crx-quickstart/launchpad/felix/cache.lock

If this also don't work, try deleting the index folder and restarting again, which will build your indexes again and might take some time to start.

Hi @chitramadan , this worked for me. only part to add is first kill java.exe process from task manager. Then remove both files repo.lock & cache.lock. Then restart the AEM instance.

I did not do anything, just deleted below file and it works.
/author/crx-quickstart/launchpad/felix/cache.lock

/publish/crx-quickstart/launchpad/felix/cache.lock doesn't help me

Hi @apoorva_arza,

Please check all the available existing error.log files(logs rotated with previous days) in your local instance before you get to notice the exact log statement - "AuthenticationSupport service missing".

Share the initial statement that logged as "Error" level.

Recently ran into the issue in one of my local instance and the original/initial cause was Java Heap Space (java.lang.OutOfMemoryError: Java heap space) which then eventually lead to "AuthenticationSupport service missing" - While setting up the new instance, I missed to configure the JVM options in start.bat and was using the default one.

I have the same error. Running AEM 6.5.X on a Windows 2016 server. The AEM instance was working fine until a reboot was performed (i am assuming AEM was not stopped properly before rebooting). Any advice? I have followed few steps identified in this blog (i.e delete Index folder, cache.lock,repo.lock) but problem is still there.

I had a similar issue. I have resolved this by activating all the bundles into active. in the system bundles, I saw a few are resolved. I have manually updated those as active and now it started working.
