rajs73651622 This is a very generic message and definitely not enough to point out the problem. However, this may signify some sort of repository inconsistency.

I would suggest you to check for SegmentNotFound errors in the error.log file and in case you find those you can refer to [1] in order to resolve the segment store inconsistencies.

[1] Fix Inconsistencies in the repository when SegmentNotFound Issue is reported in AEM 6.x

It may also occur, if you are running AEM instance with a user other than expected user. For example, instance should start using aemuser but u are starting it with root user.

Hi everyone.
This worked for me:

remove files:
/crx-quickstart/repository/segmentstore/repo.lock
/crx-quickstart/launchpad/felix/cache.lock

remove folder:
/crx-quickstart/repository/index/launchpad/config/org/apache/sling/jcr/repoinit

I hope this helps
Cheers

Hi, I am not able to delete the repo.lock file as suggested -

[siva143]

turn of the server and try to delete it will work

[subrato_kha]

this works but the folder path is incorrect for repoinit

correct path : /crx-quickstart/launchpad/config/org/apache/sling/jcr/repoinit

This worked for me

delete folders:
/author/crx-quickstart/repository/segmentstore/repo.lock
/author/crx-quickstart/launchpad/felix/cache.lock
/crx-quickstart/repository/index
/launchpad/config/org/apache/sling/jcr/repoinit

I guess the paths could be slightly different depending on versions or whatever, but the goal are the endpoints on paths
