See this https://stackoverflow.com/questions/31002612/java-hotspottm-64-bit-server-vm-warning

If you tweak the JVM Memory Arguments for your job either in Studio or TAC, and you set a higher value, then all childjobs that are "run as an independent process" will also use the same same JVM Memory arguments. And basically you server does not have enough RAM to reserve the memory. Remember, Java reserves physical RAM, and does not reserve virtual memory.

For example:

JOB A (JVM -Xmx Memory 4GB)

-- Calls Child Job B (will inherit -Xmx from Job A and will initiate with 4 GB RAM)

-- Calls Child Job C (will inherit -Xmx from Job A and will initiate with 4 GB RAM)

If Child Job B & C are being executed in Parallel, then your system needs 12 GB RAM, else your child job cannot start.

Again this if for child job run as an independent process. If you change that settings, then all 3 jobs run with Job A memory space i.e. 4GB

If you have many other jobs also running on the same server, then you should check whether you have enough RAM on the server when this Job is being scheduled and run.
