JNI DLL out of memory?

Mikael Laine

Hi all, and thanks for reading this msg.
My problem is as follows: I have a dll with some native methods that I
want to use from my JAVA-app, but allocating too big arrays results in
"An unrecoverable stack overflow has occurred."
The entire error message is lower in this message.
The piece of code I use here is essentially (I call a native method from
java that calls this):

void testbsearch(){int testarray[500000];}

How do I know it runs out of memory? Simple, because

void testbsearch(){int testarray[50000];}

works just fine, no errors. A size of 75000 didn't work either, so the
boundary is somewhere in between 50k and 75k = 100KB and 150KB of memory.

SO, MY QUESTION IS: HOW DO I GIVE MORE MEMORY TO MY DLL?
(btw. allocating big arrays in JAVA has worked just fine to a certain
limit. I tried an integer array of size 20000000 with no probs. Thats
about 40Megs of RAM used. The problem isn't with VM memory limits, then...)

The entire error message is here:
------------------------------------------------------------------------------------------
An unrecoverable stack overflow has occurred.

An unexpected exception has been detected in native code outside the VM.

That's a question to pose to the maker of your linker/compiler of the
C/C++ part. Dig around in the project settings.

Don't shout.

You are running into this limit because you are attempting to
statically allocate too much memory. Allocate the array dynamically
instead using malloc() or calloc() and you'll find that the limit is
much higher.

gets back to the limitations of C++ not Java. looks like you've overrun
your static memory limits, switch to dynamic memory allocation and
besure to free it up when you are finished.

have you read "Essential JNI" by mr. Gordon ?
