I am using AEM 6.5. I have a really weird problem on startup of the instance. Every time, when I shut off my instance and start it again, my AEM instance wouldn't work properly. The image on the splash screen as well as the icons in the touch UI wouldn't load. I had to delete the crx-quickstart to reinstall the instance. Then it will be fine. But next time, when I shut off the instance and start it again, same problem happens. I can't really delete the crx-quickstart every time since I have installed some packages and I had to redo them again. I was wondering if anyone know how to resolve this issue.
Are you migrating from old AEM version to new one? Also, please let me know if I've understood incorrectly here: --> when you have a fresh instance(just after you unpack the jar) things work quite well.
--> as soon as you install some packages and the the issue starts to happen(after you shut down the instance and restart)
Is there is a possibility that you have custom oak:index definitions in your package? if that's the case please remove those paths(custom index definitions) from filter(while creating the package itself) and then try installing it.(check if you have queryPaths and includedPaths in your custom index definition)
Also, if you leave your instance for a long while(2hours or so), does that resolve the issue on its own? please try that.
Error means something wrong with your datastore. Either the user running AEM does not have permissions to the crx-quickstart/repository/datastore folder or something else going on with the datastore.
