Out of memory error

[geraldus]

I'm facing out of memory error on my laptop running OS X Yosemite with 16 gigabyte of RAM.
I've intentded to compile my javascript app (172k lines). I've tried both SIMPLE_OPTIMIZATION and ANDVANCED_OPTIMIZATION.

My question on StackOverflow

Output listing:

$ ccjs ./static/ui.jsexe/all.js --compilation_level=ADVANCED_OPTIMIZATIONS > ./static/ui.jsexe/all.min.js

This error comes from closure compiler itself, it's thrown on the Java side of things (more memory allocated than available to the JVM). As a workaround, you could try to edit the default arguments to contain -Xms and -Xmx options, e.g. -Xms256m -Xmx1024m.

From the docs:

• The -Xms option sets the initial and minimum Java heap size. The Java heap (the “heap”) is the part of the memory where blocks of memory are allocated to objects and freed during garbage collection.
• This option sets the maximum Java heap size. The Java heap (the “heap”) is the part of the memory where blocks of memory are allocated to objects and freed during garbage collection. Depending upon the kind of operating system you are running, the maximum value you can set for the Java heap can vary.

Please let me know of your findings!

Cool! It helped! I'm not certain should that options be set by default, maybe adding command line arguments which allow such customisations would be right thing to do.
Thank you!

[dcodeIO]

Thanks, that was also my thought. I think I'll go with some reasonable defaults plus giving an option to adapt it.

[geraldus]

I'll close this for now, thanks again!

hey I set
export JVM_ARGS="-Xmx8048m -XX:MaxPermSize=2048m"
and still getting same error

@carlitux Xmx: This value must be a multiple of 1024 greater than 2MB
