Application gives a java.lang.OutOfMemoryError when run from CLI

[Bill Moo]

Hello, I have a java application written using the Eclipse IDE and when I run it from within the IDE all works as expected. However, if I run the same application from the command line then it fails while executing:

java.lang.OutOfMemoryError: Java heap space

The XML file is 14MB in size. Can you one shed some light on this?

Rather then re-type it, just read this[^].

It is not just a matter of memory that is assigned to the VM. :thumbsdown:you need to find your failure! :thumbsdown: You have somewhere in there a infinite loop. That one is creating objects / reading data / ...filling up the memory with bits and in the end crashing your application with a heap space failure. Find that loop! fix it. There is no other way around it. Debug through your code and find the never ending loop. There is no Exception defined for such a failure, so you need to find that manually. Good luck and keep us informed whether you'd find it. Coffee and chocolate helps.

Thank you for the reply but I of course should have mentioned that I have tried this. Not the VisualVM but increasing the usable memory. I can allocate a max of 320m but anything more and I get :

Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

But when it does start in this case with 320m I get

A fatal error has been detected by the Java Runtime Environment:

java.lang.OutOfMemoryError: requested 198896 bytes for Chunk::new. Out of swap space?

Internal Error (allocation.cpp:272), pid=25971, tid=8792264704

Error: Chunk::new

JRE version: 7.0

Java VM: OpenJDK 64-Bit Server VM (20.0-b03 mixed mode bsd-amd64 compressed oops)

An error report file with more information is saved as:

So I am still a bit confused, but I downloaded the VisualVM and I'll see what it can tell me. The machine is SMP running OpenBSD v5 and has 6GB of memory and 5.9G of available.

Not sure what the original problem is but the above suggests something is really wrong with your platform and/or however you are attempting to run that.
