Increase heap size first. Use correct memory parameters[1] either with jar or <crx-quickstart folder>/bin/start script when starting AEM instance.

Add/Edit below line of code in start.bat/sh file

CQ_JVM_OPTS ='-server –Xms8192m –Xmx8192m -XX:MaxPermSize=1024M

and restart the instance.

Xms is Min heap - size can be increased depending on your instance RAM size

Xmx is Max heap - size can be increased depending on your instance RAM size

MaxPermSize size can be increased depending on your instance RAM size

 

For command line looks like this:

java -Xmx1536M -jar cq6-author-4502.jar

OR first unpack jar

java -jar cq6-author-4502.jar -unpack

and then try to use the start script:

cd crx-quickstart/bin
./start

@nandheswara Increasing the heap size would fix your issue, Generally your allocated heap does not exceed 50% of your total RAM.

    Hi @bhuwan_b 

    Can you send some blog links to increase the heap size, above blog link is not working

      Hi @nandheswara , You will need to increase the heap size in stat.bat file and quickstart.bat file as mentioned below.
