Strange error sometimes after install a large package (embedded ACS common)

This means that something that was included in the package is broken. Could be anything. For example - you may have errors in the Java logic of the OSGi bundle. You need to post the log file. That will provide more information about what is wrong. 




This could be the case that something that got missing or broken while creating a package or while installing.

But to debug this in detail, please share the the AEM error.log (500 is server side problem, so you can not get much of the information at browser console, so please share the server error log).

Thanks and Regards

Thanks Steve Cavekautuksahni

The strange is that if I install only my package or only, the system will be OK. 

But when I install my package and then install (order of installation doesn't impact) then the issue happened.

Or If I embed the in my package, error also happen.

Note: The issue is on AEM 6.2 with acs-aem 3.1

(AEM 6.1 with acs-aem 2.x works well).

The issue can be resolved for now. Please refer the following link:


@thanhnk it sounds like you need to increase the "Number of Calls per Request" property of the Sling Main Servlet. This can happen if your project is especially large. It could just be that the component added by ACS AEM Commons pushes you over the default limit.
