Hi @lone_Ranger 

Update the start up script that brings up AEM server with

CQ_JVM_OPTS='-server -Xmx2048m -XX:MaxPermSize=256M -Djava.awt.headless=true'  in   crx-quickstart/bin

If did not work then Modify it to -Xmx4096m and test

If you work on local and start the server with cmd line/terminal then simply pass it in

java -Xmx2048M -jar <publish>.jar

Thanks!

During the upload the code seems to buffer a lot in memory, thus you should increase the heap available to AEM.

Hi @lone_Ranger ,

Check if your machine is having sufficient RAM, and as a good practice allocate 40% to 60% of memory to heap and 10% to MaxPermSize by updating below command.

CQ_JVM_OPTS='-server -Xmx{more than 2 GB }m -XX:MaxPermSize=10% of memory M -Djava.awt.headless=true

so if your server is having 16GBs memory have below configuration.

CQ_JVM_OPTS='-server -Xmx8192m -XX:MaxPermSize=1024M -Djava.awt.headless=true

Please let me know if you still face the issues, there are other ways to upload large size packages as well.
