Memory issues

Hey guys,

Having a hard time spinning up an image.. whatever memory I set it runs out of memory... I went up to 16gb and the process still just dies...

I haven't done anything yet and just out of the box we're having memory issues... any ideas?

Start by reproducing the out-of-memory failure when launching the image and inspect the Docker logs alongside the generated hs_err_pid14.log or related JVM error reports. Check the container and JVM memory settings implicated by the startup output; done means the image starts successfully without repeated Java native-memory allocation failures.
