Sling stops by itself after a while

I have a quickstart jar. After running it for a while, I see in the logs that Java VM is shutting down and sling is stopping. Any idea what is going on ?

My java version is 1.8 SE

I am giving Xmx 1024m while starting the jar.

yes, the app comes up. I am even able to play around a bit, but then after few mins ~11 mins in some cases or ~1 hour when I give more memory, sling shuts down by itself.

I checked the error log, it does not have any max heap errors. I can share it with you. I uploaded my error.log here. https://s3.console.aws.amazon.com/s3/object/symphony-aem/error.log?region=us-east-1&tab=overview

I know this is cumbersome, but maybe you can look towards the end of the file and might be able to tell me what is going wrong.

Support stated:

I have not seen a similar issue before.

I can say, that 1Gb of Xmx is low then a minimum requirement.

Considering that AEM 6.x use nmap mempry for tar files it is very well memory usage related issue.

How much memory is recommended ? I can try that straight away and get back to you.

Ok I am trying with 3G for Author and Publisher. I will post here if I see the same issue again.

It stopped again. This time with 3G of memory. I piped the console logs to a file and here is the output

Unable to access error.log link.

I would suggest you to create a support ticket for this as this requires some debugging.
